OPINION
These consolidated cases involve unrelated traffic stops of vehicles driven by defendants Cosby and Mendoza.
BACKGROUND
Michael Cosby
The State initially charged Cosby with unlawful possession of drug paraphernalia (720 ILCS 600/3.5 (West 2000)) and unlawful possession of cocaine (720 ILCS 570/ 402(c) (West 2000)), resulting from a search of Cosby’s vehicle and of a cigarette pack belonging to Cosby. The drug paraphernalia charge was later nol-prossed by the State. Cosby filed a motion to suppress evidence. Trial counsel and the State stipulated to the admission of the *266police report written by Officer Steven Kaus and then presented arguments to the circuit court of Will County. The police report is not in the record on appeal. However, the appellate court stated the stipulation provided that Kaus would testify that he stopped Cosby for not having a proper rear registration light. Cosby provided valid insurance information and a speeding ticket in lieu of a driver’s license. Kaus returned to his squad car and called for backup. He verified that Cosby had a valid driver’s license and that there were no outstanding warrants for his arrest. When the backup officer arrived, Kaus approached Cosby’s car, returned his speeding ticket and insurance card to him, and gave Cosby a warning for the rear light violation. Kaus then asked for consent to search Cosby’s car. Cosby consented. Kaus found drug paraphernalia in the console of the car and he arrested Cosby.
The trial court denied the motion to suppress, but did not explain its reasoning.
At Cosby’s trial, Kaus testified that at approximately 1:30 a.m. on July 12, 2001, he stopped Cosby’s car for having no rear license plate light. Cosby handed him a speeding ticket and an insurance card. Kaus went back to his squad car, where he called for backup in anticipation of requesting Cosby’s consent to search his car. About five minutes later, the backup officer arrived. Kaus went back to Cosby’s car, returned the speeding ticket and insurance card, and gave Cosby a written warning about the rear registration light. Kaus then asked Cosby for consent to search his car, which Cosby gave. Prior to searching the car, Kaus asked for and received consent from Cosby to search his person. Cosby removed all items from his pockets, Kaus inspected them, and Cosby replaced the items in his pockets. Kaus then proceeded to search Cosby’s car. Kaus found a crack pipe in the car’s center console. He placed Cosby under arrest and *267took him to the police station. There, Cosby emptied his pockets and placed his property on a tray, including a package of cigarettes. Cosby called his wife to come to the jail and post bond. As Kaus was giving Cosby back his property, he discovered four rocks of crack cocaine hidden within the cigarette packaging.
The jury convicted Cosby of the possession charge and, following a sentencing hearing, the trial court sentenced Cosby to 24 months of probation, six months in the county jail, and payment of fines. Trial counsel filed a motion to reconsider sentence, which was denied. Counsel did not file a posttrial motion.
Cosby appealed, arguing that the trial court erred in denying his motion to suppress evidence. The appellate court first addressed Cosby’s forfeiture of his argument on appeal, noting that Cosby had failed to preserve the issue in a posttrial motion. However, the appellate court elected to consider the issue, “[biased on the constitutional nature and underlying implication of the alleged error.” Relying on this court’s decision in People v. Gonzalez, 204 Ill. 2d 220 (2003), the appellate court held that Kaus’ questioning of Cosby and his search of Cosby’s car were unrelated to the circumstances justifying the stop, that Kaus lacked any reasonable, articulable suspicion that would support his further detention and questioning of Cosby, and that Kaus’ actions impermissibly prolonged Cosby’s detention and changed the fundamental nature of the stop. Accordingly, the appellate court held that the motion to suppress should have been granted. Cosby, No. 3—03—0681 (unpublished order under Supreme Court Rule 23).
Justice Schmidt dissented, arguing that Gonzalez has been implicitly overruled by the United States Supreme Court’s decision in Illinois v. Caballes, 543 U.S. 405, 160 L. Ed. 2d 842, 125 S. Ct. 834 (2005). Relying on other decisions of this court and the Supreme Court, Justice *268Schmidt would have found the search of Cosby’s car legal on the basis of a valid consent.
We granted the State’s petition for leave to appeal (210 Ill. 2d R. 315(a)).
Hugo Mendoza
Mendoza was charged in the circuit court of Kane County with unlawful use of a weapon (720 ILCS 5/24—1.6(a)(1), (a)(3)(A) (West 2002)). Mendoza’s trial counsel filed a motion to suppress evidence. A hearing on that motion was held, at which two police officers testified. At about 11 p.m. on May 10, 2004, two Aurora police officers, Inspectors Jeff Wiencek and Joe Weber, observed Mendoza driving his Pontiac Grand Prix sedan. They noted that the car’s rear license plate cover was tinted, in violation of Illinois law. They also noticed a red bandana hanging from the rearview mirror of Mendoza’s car, which they considered a gang symbol of the Vice Lords. In addition, the officers determined the bandana to be large enough to obstruct Mendoza’s view, which was also a violation of Illinois law. The officers pulled Mendoza over. Pursuant to their request, Mendoza handed them his driver’s license and proof of insurance.
After determining that the license and insurance card were valid and that Mendoza had no outstanding warrants, the officers decided to ask Mendoza for permission to search his car. In explaining this decision, Wiencek, who had been a gang investigator for seven years, testified that the neighborhood was known for its gang activity. Although Wiencek did not know whether Mendoza was a gang member, he knew from covert surveillance, police reports, and interviewing people that Mendoza was an “affiliate” of the Vice Lords. Mendoza had been seen in the presence of gang members. The bandana hanging from Mendoza’s rearview mirror was red, which was one of the colors used by the Vice Lords. Using the bandana was one way of signifying affiliation with the *269gang. The officers were concerned that Mendoza might have a gun in his car. After checking Mendoza’s driver’s license and insurance, the officers returned to the car, one on each side. Weber returned Mendoza’s license and insurance card, gave him a verbal warning, and asked him if he had anything illegal in the car. Mendoza responded that he did not. Weber then asked Mendoza for permission to search his car. Mendoza refused consent.
Meanwhile, Wiencek, who was standing on the passenger side of the car, shined his flashlight inside the car and saw the butt of a gun sticking out from under the driver’s seat between Mendoza’s feet. Not wanting to create a hostile situation by drawing his gun on Mendoza, Wiencek tried to surreptitiously signal Weber to the presence of the gun. However, Weber was talking to Mendoza and Wiencek could not get Weber’s attention. After Mendoza refused consent to search his car, Weber told him he was free to leave. Mendoza started to drive away and Wiencek told Weber about the gun. Weber yelled at Mendoza to stop, but he did not. The two officers got into their squad car and drove after Mendoza. Wiencek could see Mendoza’s head and shoulders moving, but could not tell what he was doing. Weber did not notice any movement. The officers pulled Mendoza over again. They ordered Mendoza to exit the car. They handcuffed him and patted him down. Wiencek searched the car. Although Wiencek did not find a gun under the driver’s seat, he found a handgun underneath a plastic tray in the center console of Mendoza’s car.
The trial court, relying on Gonzalez, granted Mendoza’s motion, concluding that Weber’s questions to Mendoza after the traffic stop was concluded were neither related to the traffic stop nor justified by a reasonable suspicion of additional criminal activity. Since the gun was not discovered until the officers had already violated *270the fourth amendment by their questioning of Mendoza, the trial court found that the gun would not have been discovered absent the violation. The State appealed.
The appellate court rejected the trial court’s reliance on Gonzalez. However, the court nonetheless affirmed the trial court’s grant of Mendoza’s motion to suppress. The court reasoned that Gonzalez only applies to traffic stops that are still ongoing. Once Weber returned Mendoza’s driver’s license and insurance card to him, the traffic stop concluded and Mendoza was free to leave. Thus, the proper inquiry is whether Weber’s questioning amounted to a second seizure. Questioning constitutes a seizure if, in light of the circumstances, a reasonable person would not have felt free to leave. If there is a seizure, the fourth amendment is violated if there is no constitutional justification for it. The appellate court concluded that Mendoza was seized, noting the presence of more than one officer, that Mendoza was not told he was free to leave, that the officers used a “flanking maneuver” in which one officer stood on each side of the car, and that Wiencek shined a flashlight into the car. The court further found that the officers lacked either probable cause or a reasonable articulable suspicion that Mendoza had committed or was about to commit a crime. The court noted that Wiencek did not see the gun until after Mendoza was seized. Thus, this fact could not support the seizure of Mendoza once the traffic stop was concluded. Mendoza, 364 Ill. App. 3d 564, 581. We allowed the State’s petition for leave to appeal (210 Ill. 2d R. 315(a)) and consolidated this case with the appeal in People v. Cosby.
ANALYSIS
Standard of Review
This court recently set forth the applicable principles in People v. Luedemann, 222 Ill. 2d 530 (2006):
*271“In reviewing a trial court’s ruling on a motion to suppress evidence, we apply the two-part standard of review adopted by the Supreme Court in Ornelas v. United States, 517 U.S. 690, 699, 134 L. Ed. 2d 911, 920, 116 S. Ct. 1657, 1663 (1996). Under this standard, a trial court’s findings of historical fact should be reviewed only for clear error, and a reviewing court must give due weight to any inferences drawn from those facts by the fact finder. Ornelas, 517 U.S. at 699, 134 L. Ed. 2d at 920, 116 S. Ct. at 1663. In other words, we give great deference to the trial court’s factual findings, and we will reverse those findings only if they are against the manifest weight of the evidence. People v. Sorenson, 196 Ill. 2d 425, 431 (2001). A reviewing court, however, remains free to undertake its own assessment of the facts in relation to the issues and may draw its own conclusions when deciding what relief should be granted. People v. Pitman, 211 Ill. 2d 502, 512 (2004). Accordingly, we review de novo the trial court’s ultimate legal ruling as to whether suppression is warranted. Ornelas, 517 U.S. at 699, 134 L. Ed. 2d at 920, 116 S. Ct. at 1663; Pitman, 211 Ill. 2d at 512; Sorenson, 196 Ill. 2d at 431.” Luedemann, 222 Ill. 2d at 542-43.
People v. Cosby, No. 100681
Initially, we note that Cosby failed to file a posttrial motion raising the issue of the trial court’s denial of his motion to suppress evidence. Instead, his trial counsel filed only a motion to reconsider sentence. The State argues that Cosby has therefore forfeited any argument that the trial court erred in denying his motion to suppress. It also argues that the appellate court should not have addressed Cosby’s argument.
To preserve an alleged error for review, a defendant must raise a timely objection at trial and raise the error in a written posttrial motion. People v. Enoch, 122 Ill. 2d 176, 186 (1988). This long-standing rule is consistent with section 116—1 of the Code of Criminal Procedure of 1963 (725 ILCS 5/116—1 (West 2006) (governing procedure for filing motion for new trial)) and serves the *272purpose of allowing the trial court “ ‘the opportunity to grant a new trial, if warranted.’ ” Enoch, 122 Ill. 2d at 186, quoting People v. Caballero, 102 Ill. 2d 23, 31-32 (1984). Nonetheless, in a criminal case, an issue not properly preserved may still be raised on appeal under Supreme Court Rule 615(a) (134 Ill. 2d R. 615(a)), which provides:
“Any error, defect, irregularity, or variance which does not affect substantial rights shall be disregarded. Plain errors or defects affecting substantial rights may be noticed although they were not brought to the attention of the trial court.”
The appellate court did not engage in plain-error review. Instead, the court reviewed Cosby’s forfeited argument “[b]ased on the constitutional nature and underlying implication of the alleged error.”
This court conducted an extensive review of the plain-error rule in People v. Herron, 215 Ill. 2d 167 (2005), where we stated:
“The plain-error doctrine, as it has developed in Illinois, allows a reviewing court to reach a forfeited error affecting substantial rights in two circumstances. First, where the evidence in a case is so closely balanced that the jury’s guilty verdict may have resulted from the error and not the evidence, a reviewing court may consider a forfeited error in order to preclude an argument that an innocent person was wrongly convicted. [Citation.] Second, where the error is so serious that the defendant was denied a substantial right, and thus a fair trial, a reviewing court may consider a forfeited error in order to preserve the integrity of the judicial process. [Citations.] This so-called disjunctive test does not offer two divergent interpretations of plain error, but instead two different ways to ensure the same thing — namely, a fair trial.” Herron, 215 Ill. 2d at 178-79.
The appellate court emphasized the constitutional nature of the alleged error in deciding to review Cosby’s argument despite his forfeiture. However, the mere fact that an alleged error affects a constitutional right does *273not provide a separate ground for review, for “even constitutional errors can be forfeited.” People v. Allen, 222 Ill. 2d 340, 352 (2006). Thus, the appellate court erred in addressing Cosby’s forfeited argument on this basis.
However, we note that the first step in plain-error review is to determine whether error occurred. People v. Piatkowski, 225 Ill. 2d 551, 565 (2007) (“the first step is to determine whether error occurred in the giving of the instruction”). Absent reversible error, there can be no plain error. Herron, 215 Ill. 2d at 187; People v. Williams, 193 Ill. 2d 306, 349 (2000). Accordingly, we first determine whether any error occurred in Cosby’s case.
The fourth amendment to the United States Constitution guarantees the “right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures.” U.S. Const., amend. IV In addition, article I, section 6, of the Illinois Constitution of 1970 provides that “[t]he people shall have the right to be secure in their persons, houses, papers and other possessions against unreasonable searches, seizures, invasions of privacy or interceptions of communications by eavesdropping devices or other means.” Ill. Const. 1970, art. I, §6.
Initially, we must determine the proper framework for our analysis. The United States Supreme Court has characterized the detention by police of individuals during a traffic stop as a “seizure” of “persons” within the meaning of the fourth amendment. Berkemer v. McCarty, 468 U.S. 420, 436-37, 82 L. Ed. 2d 317, 332-33, 104 S. Ct. 3138, 3148 (1984), citing Delaware v. Prouse, 440 U.S. 648, 653, 59 L. Ed. 2d 660, 667, 99 S. Ct. 1391, 1396 (1979). A person is seized when, by means of physical force or a show of authority, the person’s freedom of movement is restrained. United States v. Mendenhall, 446 U.S. 544, 553, 64 L. Ed. 2d 497, 509, 100 S. Ct. 1870, *2741877 (1980). The Supreme Court further elaborated on that point:
“We conclude that a person has been ‘seized’ within the meaning of the Fourth Amendment only if, in view of all of the circumstances surrounding the incident, a reasonable person would have believed that he was not free to leave. Examples of circumstances that might indicate a seizure, even where the person did not attempt to leave, would be the threatening presence of several officers, the display of a weapon by an officer, some physical touching of the person of the citizen, or the use of language or tone of voice indicating that compliance with the officer’s request might be compelled.” Mendenhall, 446 U.S. at 554, 64 L. Ed. 2d at 509, 100 S. Ct. at 1877.
This court adopted the Mendenhall factors in People v. Murray, 137 Ill. 2d 382, 390 (1990).
In Berkemer, a case involving the application of Miranda v. Arizona, 384 U.S. 436, 16 L. Ed. 2d 694, 86 S. Ct. 1602 (1966), to traffic stops, the Supreme Court observed that the “usual traffic stop” is more analogous to a so-called Terry stop (see Terry v. Ohio, 392 U.S. 1, 20 L. Ed. 2d 889, 88 S. Ct. 1868 (1968)) than to a formal arrest. Berkemer, 468 U.S. at 439, 82 L. Ed. 2d at 334, 104 S. Ct. at 3150. However, the Court cautioned in a footnote that “[n]o more is implied by this analogy than that most traffic stops resemble, in duration and atmosphere, the kind of brief detention authorized in Terry. We of course do not suggest that a traffic stop supported by probable cause may not exceed the bounds set by the Fourth Amendment on the scope of a Terry stop.” Berkemer, 468 U.S. at 439 n.29, 82 L. Ed. 2d at 334 n.29, 104 S. Ct. at 3150 n.29.
Nonetheless, this court and many other courts have analyzed traffic stops under Terry principles, regardless of whether the initial stop was supported by probable cause or reasonable suspicion. See, e.g., People v. Gonzalez, 204 Ill. 2d 220 (2003) (and cases cited therein); People v. Bunch, 207 Ill. 2d 7 (2003).
*275In Gonzalez, this court applied Terry principles to a traffic stop during which a police officer requested identification from the defendant, who was a passenger in the stopped vehicle. Citing Berkemer, we noted that, because the usual traffic stop is more analogous to a Terry investigative stop than to a formal arrest, a fourth amendment challenge to the reasonableness of a traffic stop is analyzed under Terry principles. A Terry analysis involves a dual inquiry: (1) whether the officer’s action was justified at its inception, and (2) whether the action was reasonably related in scope to the circumstances that justified the interference in the first place. Gonzalez, 204 Ill. 2d at 228-29. We concluded that the officers’ stop of the vehicle was supported by probable cause. Thereafter, we set forth an analytical framework to use in determining whether police questioning during a traffic stop violates the fourth amendment. First, with respect to Terry’s scope requirement, a court must determine whether the questioning is related to the initial justification for the stop. If the questioning is so related, no fourth amendment violation occurs. If the questioning is not reasonably related to the purpose of the stop, the court must determine whether the officer had a reasonable, articulable suspicion that would justify the questioning. If so, there is no fourth amendment violation. In the absence of a reasonable, articulable suspicion, the court must consider whether, in light of the totality of the circumstances, the questioning impermissibly prolonged the detention or changed the fundamental nature of the stop. Gonzalez, 204 Ill. 2d at 235.
The State argues that this case is not controlled by Gonzalez. Alternatively, the State also argues that if this court finds that a Gonzalez analysis is required, we should reconsider Gonzalez and overrule it as inconsistent with fourth amendment jurisprudence. The State also contends that Gonzalez has been implicitly overruled by *276the United States Supreme Court’s decision in Illinois v. Caballes, 543 U.S. 405, 160 L. Ed. 2d 842, 125 S. Ct. 834 (2005).
We have very recently held in People v. Harris, 228 Ill. 2d 222, 240 (2008), that our decision in Gonzalez has been “unequivocally overruled” by the United States Supreme Court’s decision in Muehler v. Mena, 544 U.S. 93, 161 L. Ed. 2d 299, 125 S. Ct. 1465 (2005). As we noted in Harris, Muehler makes clear that the Court, in Caballes, rejected the reasoning that led to this court’s adoption of the “ ‘fundamental alteration of the nature of the stop’ ” portion of the “ ‘scope’ ” prong of Gonzalez and that all that remains of the scope prong is the “duration” portion of that analysis. Harris, 228 Ill. 2d at 242. Thus we overruled Gonzalez to the extent it holds that the reasonableness of a traffic stop must be judged by whether the officer’s conduct altered the fundamental nature of the stop. Harris, 228 Ill. 2d at 244.
The appellate court in Cosby’s case found that the traffic stop was unreasonably prolonged. While Cosby argues before this court that there was no break between the conclusion of the traffic stop and the officer’s request for consent to search, we conclude that the record does not support such an argument. The requests for consent to search in both of the instant cases followed the officers’ returning of the defendants’ paperwork. At that point, the traffic stops came to an end. The relevant question is whether the officers’ actions after the initial traffic stops had concluded constituted a second seizure of either defendant.
Thus, the question before us in Cosby’s case is whether Kaus’ request to search Cosby’s car after the traffic stop had ended constituted a new seizure for fourth amendment purposes. We analyze this question under the principles set forth in Brownlee and Menden-hall.
*277In Brownlee, the defendant was a passenger in a car stopped by two police officers for traffic violations. After securing identification from the driver and all passengers and determining that no outstanding warrants existed, the officers decided not to issue any traffic citations. The officers returned to the car, one on each side. One officer returned to the driver his driver’s license and insurance card and explained that no citations would be issued. Then, the officers paused for a couple of minutes, saying nothing. They continued to stand one on each side of the car. Following this pause, one of the officers requested permission to search the car. The driver asked whether he had a choice in the matter, to which the requesting officer answered that he did. The driver consented to the search. The officers found marijuana and an open beer bottle in the car. The officers arrested the car’s occupants and, during a search of the defendant’s person incident to her arrest, they found cocaine. People v. Brownlee, 186 Ill. 2d 501, 506-07 (1999).
The trial court granted the defendant’s motion to quash her arrest and suppress evidence; the appellate court reversed and remanded. Applying Terry principles to the officers’ actions following the conclusion of the traffic stop, this court concluded that the officers effected a seizure of the car’s occupants by flanking the car while saying nothing for a period of two minutes. Citing Mendenhall, we noted that a person is seized when, in view of all the facts and circumstances, the person would not feel free to leave. Brownlee, 186 Ill. 2d at 517. Because the officers had no probable cause or reasonable suspicion to detain the occupants, this show of authority constituted an illegal seizure in violation of the fourth amendment. Under the circumstances, this court found that a reasonable person would have concluded that he or she was not free to leave. Brownlee, 186 Ill. 2d at 520.
We do not find the presence of any of the Mendenhall *278factors in Cosby’s case. Cosby argues that the presence of two police officers suggests coercion. That there were two officers present here, however, does not weigh in favor of finding a seizure. Mendenhall referenced the presence of “several” officers. In Luedemann, one officer approached a parked car in which the defendant was sitting. When the officer observed signs of intoxication, he radioed for backup. Another officer arrived on the scene and the officers approached the defendant’s car, one on each side. In discussing whether the defendant was seized by the officers’ actions, this court noted that none of the Mendenhall factors were present. Luedemann, 222 Ill. 2d at 553. It is clear, then, that the presence of only two officers, without more, is not a factor that would indicate a seizure occurred.
There is no indication in the record that either of the officers touched Cosby’s person, that they displayed their guns, or that Kaus used language or a tone of voice indicating to Cosby that he had no choice but to consent to the search of his car. Cosby emphasizes that Kaus did not tell him that he was free to leave prior to requesting consent to search. However, while this is a factor to consider, the Supreme Court has held that such advice is not required. See Ohio v. Robinette, 519 U.S. 33, 35, 136 L. Ed. 2d 347, 352, 117 S. Ct. 417, 419 (1996).
Cosby also argues that he did not feel free to leave because Kaus treated the request to search as if it were part of the traffic stop. Cosby maintains that the officer asked for consent to search “in the same breath” as he explained the warning and returned Cosby’s paperwork to him. According to Cosby, this made it less likely that he would feel free to leave. However, the appellate court’s recitation of the stipulated police report that formed the basis of the suppression hearing does not support this argument. In addition, at Cosby’s trial, Kaus simply testified that he “explained the nature of the written warn*279ings for no license plate light. I gave him hack his paperwork, and then I asked him consent to search the Pontiac.” This testimony simply indicates that shortly after returning Cosby’s paperwork to him, Kaus requested consent to search the car.
Cosby further argues that all of the circumstances of the traffic stop, taken together, strongly suggest that he was not free to leave at the time Kaus requested consent to search. Cosby highlights the following: (1) the presence of two officers; (2) the stop took place in the early morning hours in a deserted and poorly lit locale; and (3) the officers’ “double teaming” of Cosby at his car at the time of the request. Cosby asserts that the two officers were standing on either side of his car at the time Kaus requested to search the car. However, the record contains no suggestion that the officers surrounded the car, as Cosby claims. Thus, Cosby’s citation of this court’s decision in People v. Gherna, 203 Ill. 2d 165 (2003), is unavailing. There, two police officers on bicycles positioned themselves on either side of the defendant’s truck, questioned the defendant and her daughter about their identities, and eventually asked the defendant to exit the vehicle for further questioning. This court held that, under the totality of the circumstances, these actions constituted a show of authority to which a reasonable person would feel compelled to submit. We noted that the positioning of the officers and their bicycles prevented the defendant from either exiting her vehicle or driving away. Gherna, 203 Ill. 2d at 180.
In his partial concurrence and partial dissent, Justice Freeman accuses the majority of relying exclusively on the factors set forth in the Mendenhall decision in determining that Cosby was not seized when he was asked for consent to search his car. The dissent quotes our decision in Luedemann, where we said that the Men-denhall factors “ ‘are not exhaustive and that a seizure *280can be found on the basis of other coercive police behavior that is similar to the Mendenhall factors.’ ”231 Ill. 2d at 296 (Freeman, J., concurring in part and dissenting in part, joined by Kilbride and Burke, JJ.), quoting Luedemann, 222 Ill. 2d at 557. The dissent observes that we noted other factors in addition to those set forth in Mendenhall that may indicate a seizure of the occupants “of a parked vehicle.” Luedemann noted that courts have developed additional rules that are applicable to “police approaches of occupants of parked vehicles.” Luedemann, 222 Ill. 2d at 557. Those factors include boxing the vehicle in, approaching it on all sides by many officers, pointing a gun at the suspect, and ordering the suspect to place his or her hands on the steering wheel, or the use of flashing lights as a show of authority. Luedemann, 222 Ill. 2d at 557.
The additional factors, however, only apply to situations where police approach a parked vehicle, which was the case in Luedemann. The fact that Cosby’s car was parked on the side of the road after Kaus effected a traffic stop does not make the additional factors applicable. However, even were those factors to be applied, it is clear that only one of them — flashing lights — is present in Cosby’s case. The officers here did not box Cosby’s car in; both officers’ cars were located behind Cosby’s car. His car was not approached on all sides and there were two officers, not many. There is no evidence that either officer pointed a gun at Cosby and no evidence that Cosby was ordered to place his hands on the steering wheel.
The dissent complains that, by focusing on the Men-denhall factors and by not considering the additional factors set forth in Luedemann, the majority leaves the impression that the Mendenhall factors are the exhaustive factors for determining whether a person is seized within the meaning of the fourth amendment. The dissent is concerned that our reliance upon the Mendenhall *281factors “calls into question the continued viability of our analysis in Luedemann, a unanimous decision that is less than two years old.” 231 Ill. 2d at 301 (Freeman, J., concurring in part and dissenting in part, joined by Kilbride and Burke, JJ.). It is true that the Mendenhall factors are not exhaustive and that a seizure may be found on the basis of other coercive police conduct similar to the Mendenhall factors. Luedemann, 222 Ill. 2d at 557. However, we note that Luedemann itself addressed the effect that use of the Mendenhall factors has on the analysis of whether a seizure occurred. We noted that this court, in Murray, adopted the factors, reviewed each of the factors, found that they were absent, and concluded that no seizure had occurred. Luedemann, 222 Ill. 2d at 553-54. In addition, Luedemann noted that this court in People v. Smith, 214 Ill. 2d 338, 353-54 (2005), relied on the absence of the Mendenhall factors to conclude that no seizure had taken place. Luedemann, 222 Ill. 2d at 554. We further observed:
“Indeed, Mendenhall itself used an analysis based on the absence of Mendenhall factors. The lead opinion listed the four factors, noted their absence, and then concluded that no seizure had occurred. [Citation.] From the very minute the Mendenhall factors were created, courts have used their absence to determine that seizures had not occurred.
Even in the absence of cases such as Mendenhall, Murray, and Smith, it would seem self-evident that the absence of Mendenhall factors, while not necessarily conclusive, is highly instructive. If those factors are absent, that means that only one or two officers approached the defendant, they displayed no weapons, they did not touch the defendant, and they did not use any language or tone of voice indicating that compliance with their requests was compelled. Obviously, a seizure is much less likely to be found when officers approach a person in such an inoffensive manner.” (Emphasis in original.) Luedemann, 222 Ill. 2d at 554.
Despite the absence of any of the Mendenhall factors in Cosby’s case, the dissent expresses the belief that we *282must look to the totality of the circumstances to determine whether Cosby was seized at the time Kaus asked him for consent to search his car. This court in Luede-mann addressed a similar contention which had been made by the appellate court in that case:
“The appellate court believed that, because Mendenhall stated that courts should look to the totality of the circumstances in determining whether a seizure had occurred, the court must conduct a ‘practical, realistic’ inquiry to determine if a reasonable person would have felt free to leave and that the court should not focus on rigid, technical rules such as the Mendenhall factors. [Citation.] The problem with this view is that, immediately after Mendenhall said that a person is seized if ‘in view of all of the circumstances surrounding the incident, a reasonable person would have believed that he was not free to leave’ [citation], it elaborated on how courts are to make that determination. The lead opinion listed several factors that are generally indicative of a seizure, said that in the absence of some such evidence otherwise inoffensive contact between a member of the public and the police is not a seizure, and then concluded that no seizure had occurred because those factors were not present. [Citation.] This court expressly adopted those factors in Murray. The ‘in view of all the circumstances’ language must be read in concert with, not in opposition to, the factors. [Citation.] The factors illustrate what type of police conduct would give a reasonable person an objective reason to believe that he or she was not free to leave or was not free to decline an officer’s requests.” Luedemann, 222 Ill. 2d at 554-55.
The reality in Cosby’s case is that none of the Men-denhall factors are present. Therefore, the dissent’s insistence that Cosby was seized is not supported by the record.
The dissent faults the majority for not citing this court’s decision in Bunch, which the dissent views as similar to Cosby’s situation. However, in Bunch, the defendant was removed from the car and directed to stand at the rear of the car alongside the handcuffed *283driver. The officer stood a foot away from the defendant and shined his flashlight in the defendant’s face, while asking him questions. This court considered the officer’s actions to be coercive in nature and to constitute a show of authority, such that, even though the traffic stop had come to an end, the defendant was seized anew. Bunch, 207 Ill. 2d at 19-20. The facts in Bunch are not at all analogous to those in Cosby’s case. Thus, Bunch provides no authority for the dissent’s conclusion that Cosby was seized at the time Officer Kaus requested permission to search.
The dissent also cites this court’s decision in Brown-lee, which it contends supports its conclusion. However, Brownlee is no more applicable than Bunch. In Brownlee, after the driver had been handed back his paperwork by one of the two officers and had been told that no ticket would be issued, both officers, who were on opposite sides of the vehicle, stood at their stations, saying nothing. After about two minutes had elapsed, the officer standing next to the driver’s door asked for permission to search the vehicle. After asking whether he had a choice, the driver consented. This court held that the officers’ actions constituted a show of authority and that a reasonable person in the driver’s position would not have felt free to leave. Thus, the driver and his passengers were subjected to a seizure. Brownlee, 186 Ill. 2d at 520-21.
Here, the record shows only that Officer Kaus approached Cosby’s vehicle, returned his paperwork and asked for consent to search. There is no indication in the record that Kaus waited for any particular period of time before asking for consent. Thus, Brownlee is not analogous for two reasons — the record does not support any inference that both officers flanked Cosby’s vehicle and there was no show of authority like that in Brownlee, where both officers flanked the vehicle and waited for two minutes before asking for consent to search.
*284The dissent also criticizes our rejection of Cosby’s argument that Officer Kaus extended the traffic stop beyond its lawful purpose because he asked for consent to search nearly simultaneously with returning Cosby’s identification and proof of insurance. The dissent notes that, during argument on Cosby’s motion to suppress, the prosecutor told the circuit court that Kaus “asked for consent and got the consent almost immediately as he is handing the citation to the defendant.” 231 Ill. 2d at 290 (Freeman, J., concurring in part and dissenting in part, joined by Kilbride and Burke, JJ.). Arguments, of course, are not evidence. The prosecutor’s statement was an attempt to answer defense counsel’s citation of Brown-lee to the court as being similar to Cosby’s case. Counsel had argued that the action of Officer Kaus in calling for backup without any reasonable suspicion of criminal activity was essentially a show of authority by Kaus indicating to Cosby that he did not have the right to leave and that he must consent to the search. The prosecutor’s statement was, at most, his own interpretation of matters contained in the police report. We do not know what is contained in the police report because it is not in the record on appeal. However, we do know that, at the trial, no testimony was elicited on direct or cross-examination as to the timing of Officer Kaus’ request for consent to search as it related to the returning to Cosby of his paperwork. Nothing in Kaus’ testimony gives rise to any inference one way or the other. Accordingly, to the extent the dissent’s conclusions about the duration of the traffic stop and Cosby’s alleged seizure depend on the belief that Officer Kaus simultaneously requested consent to search as he was handing Cosby his paperwork, they are unsupported by the record. For all these reasons, we respectfully disagree with the dissent’s conclusions.
Accordingly, applying the principles of Brownlee and *285 Mendenhall, we conclude that Cosby was not seized and that his consent to search his car was therefore voluntary. The trial court’s decision denying Cosby’s motion to suppress was therefore not in error. Because no error occurred, we need not consider the application of plain error to this appeal.
People v. Mendoza, No. 102584
Initially, we note that Mendoza has not filed an appellee’s brief in this court. Nonetheless, we will decide the merits of this appeal under the principles set forth in First Capitol Mortgage Corp. v. Talandis Construction Corp., 63 Ill. 2d 128, 133 (1976) (where the record is simple and the claimed errors are such that the reviewing court can decide them without the assistance of an appellee’s brief, the court should address the merits of the appeal).
The trial court here applied the Gonzalez analysis to the facts surrounding the traffic stop of Mendoza’s car and granted Mendoza’s motion to suppress. While the appellate court agreed with the result reached by the trial court, the appellate court disagreed as to the application of Gonzalez to the facts of the case. The appellate court concluded that, by its very terms, Gonzalez applies only to police questioning during a traffic stop. The court noted that Gonzalez involved police questioning of a passenger during the traffic stop, whereas in the present case, the traffic stop had concluded prior to Weber’s asking Mendoza for permission to search his car. Thus, according to the appellate court, the proper inquiry is whether Weber’s questions amounted to a second seizure. The court opined that the proper analysis to apply to that inquiry is the one set forth by this court in Brownlee. The court then concluded that Mendoza was seized and the evidence recovered from his car must be suppressed. Mendoza, 364 Ill. App. 3d at 574.
It is clear that the traffic stop of Mendoza’s car had *286come to an end prior to the questioning of Mendoza by Weber. In addition, we note there is no evidence that the officers unreasonably prolonged the traffic stop beyond the time required to fulfill its initial purpose. Therefore, we will apply the Brownlee analysis to Mendoza’s appeal.
The State argues that Mendoza was not seized when Weber asked him if he had anything illegal in his car and requested consent to search. According to the State, the traffic stop ended when Weber returned Mendoza’s driver’s license and insurance card to him and gave him a verbal warning. At that point, Mendoza was no longer seized and he was free to leave. The State notes Mendoza’s refusal to consent to a search of his car in support of its argument that Mendoza was not restrained by Weber’s questions. The State further notes the absence of any of the Mendenhall factors as support for its argument.
There is no question that the initial stop of Mendoza’s vehicle was supported by probable cause. The officers observed that Mendoza’s car had a tinted rear license plate cover and a bandana hanging from the rearview mirror, which the officers believed obstructed Mendoza’s view. As noted by the appellate court, these are violations of the traffic laws. Once Weber returned Mendoza’s driver’s license and insurance card to him, the purpose of the traffic stop was concluded. At that point, Weber asked Mendoza if there was anything illegal in his car, to which Mendoza replied that there was not. Weber then requested consent to search Mendoza’s car. Mendoza refused. Weber then advised Mendoza that he was free to leave.
The appellate court, in finding that Mendoza was seized, focused on the following factors: (1) it was late at night; (2) the officers used a flanking maneuver in approaching Mendoza’s car the second time; (3) the officers were dressed in dark, special operations uniforms with *287the word “POLICE” stenciled on them in large white letters; (4) the officers’ guns were visible; and (5) Wiencek shined his flashlight into Mendoza’s car. In view of these circumstances, the appellate court concluded that a reasonable person would not have felt free to leave. Mendoza, 364 Ill. App. 3d at 578.
As we have noted, the Supreme Court set forth in Mendenhall certain factors the presence of which would tend to indicate that a seizure had occurred. None of these factors are present in Mendoza’s case. Again, these factors are: (1) the threatening presence of several officers; (2) the display of a weapon by an officer; (3) some physical touching of the person of the citizen; and (4) the use of language or tone of voice indicating that compliance with the officer’s request might be compelled. Men-denhall, 446 U.S. at 554, 64 L. Ed. 2d at 509, 100 S. Ct. at 1877.
Here, there were only two officers present, not several. The appellate court noted that the officers’ guns were visible. However, it is well known that police officers carry guns. The mere fact that they do so does not mean that they have thereby displayed the guns in the manner contemplated by Mendenhall. In any event, we note that Wiencek testified he did unholster his gun when he thought he saw the butt of a gun on the floorboard of Mendoza’s car. However, he testified that he did not display the gun to Mendoza. Neither officer testified to any physical touching of Mendoza’s person. Finally, there is no suggestion that either officer spoke to Mendoza in such a manner as to convey to him the need for compliance with Weber’s request to search the car. The absence of this last factor is buttressed by the fact that Mendoza refused Weber’s request to search, indicating that Mendoza did not feel the need to comply with that request. The absence of all the Mendenhall factors strongly suggests that Mendoza was not seized for fourth amendment purposes.
*288The appellate court emphasized the fact that Weber did not tell Mendoza that he was free to leave after returning his driver’s license and insurance card to him. As we have stated, however, the fourth amendment does not require that an officer do so. See Robinette, 519 U.S. at 35, 136 L. Ed. 2d at 352, 117 S. Ct. at 419. The appellate court attached some significance to the fact that Wiencek shined his flashlight into Mendoza’s car. However, we have previously rejected an argument that shining a flashlight into a car at night is a factor to be considered in determining whether a seizure occurred. See Luedemann, 222 Ill. 2d at 560-61, citing Texas v. Brown, 460 U.S. 730, 739-40, 75 L. Ed. 2d 502, 512, 103 S. Ct. 1535, 1542 (1983).
We reject the appellate court’s conclusion that Mendoza was seized by the officers’ words and actions following the return of his driver’s license and insurance card. Accordingly, the subsequent discovery of the gun, the second stopping of Mendoza’s car, and the officers’ search of the car did not violate Mendoza’s fourth amendment rights.
