The pertinent provisions of G.S. 14-273 are:
“If any person shall wilfully interrupt or disturb any public or private school * * * either within or without the place where such * * * school is held * * * he shall be guilty of a misdemeanor, and shall, upon conviction, be fined or imprisoned or both in the discretion of the court.”
The defendants argue in their brief that this statute is void because its prohibitions are uncertain, vague or indefinite, under the rule applied by this Court in State v. Furio, 267 N.C. 353, 148 S.E. 2d 275. They argue in their brief that the statute contains no definition of “interrupt” or of “disturb” and, consequently, men of common intelligence must necessarily guess at its meaning and thus be left in doubt as to what conduct is prohibited. It is difficult to believe that the defendants are as mystified as to the meaning of these ordinary English words as to they profess to be in their brief. Clearly, they have grossly underestimated the powers of comprehension possessed by “men of common intelligence.” Nevertheless, we treat this contention as having been seriously made.
It is elementary that in the construction of a statute words are to be given their plain and ordinary meaning unless the context, or the history of the statute, requires otherwise. Cab Co. v. Charlotte, 234 N.C. 572, 68 S.E. 2d 433; In re Nissen’s Estate, 345 F. 2d 230. While the meaning of “interrupt” and of “disturb” is perhaps more easily understood than defined with precision, resort to Webster’s Dictionary reveals that “interrupt” means “to break the uniformity or continuity of; to break in upon an action,” and “disturb” means “to throw into disorder.” For those who are unhappy without citation to authorities of the type customarily cited in judicial opinions, we refer to Black’s Law Dictionary and to Watkins v. Manufacturing Co., 131 N.C. 536, 42 S.E. 983, where this Court said that an allegation in a complaint for personal injury that the plaintiff had been “disturbed in body” must be understood to mean that “her body was thrown into a state of disorder, and thereby injured.”
In Kovacs v. Cooper, 336 U.S. 77, 69 S. Ct. 448, 93 L. Ed. 513, the Supreme Court of the United States, speaking through Mr. *154Justice Reed, in sustaining a conviction in the courts of the State of New Jersey for violation of an ordinance forbidding the use of sound trucks emitting "loud and raucous” sound, said:
“The contention that the section is so vague, obscure and indefinite as to be unenforceable merits only a passing reference. This objection centers around the use of the words ‘loud and raucous.’ While these are abstract words, they have through daily use acquired a content that conveys to any interested person a sufficiently accurate concept of what is forbidden.”
When the words “interrupt” and “disturb” are used in conjunction with the word “school,” they mean to a person of ordinary intelligence a substantial interference with, disruption of and confusion of the operation of the school in its program of instruction and training of students there enrolled. We found no difficulty in applying. this statute, in accordance with this construction, to the activities of a group of white defendants in State v. Guthrie, 265 N.C. 659, 144 S.E. 2d 891. Obviously, the statute applies in the same manner regardless of the race of the defendant. In State v. Ramsay, 78 N.C. 448, in affirming a conviction for the similar offense of disturbing public worship, this Court, speaking through Smith, C.J., said:
“It is not open to dispute whether the acts of the defendant were a disturbance in the sense that subjects him to a criminal prosecution, and that the jury was warranted in so finding, when they had the admitted effect of breaking up the congregation and frustrating altogether the purposes for which it had convened.”
Giving the words of G.S. 14-273 their plain and ordinary meaning, it is apparent that the elements of the offense punishable under this statute are: (1) Some act or course of conduct by the defendant, within or without the school; (2) an actual, material interference with, frustration of or confusion in, part or all of the program of a public or private school for the instruction or training of students enrolled therein and in attendance thereon, resulting from such act or conduct; and (3) the purpose or intent on the part of the defendant that his act or conduct have that effect. One, who has reached the age of responsibility for his acts and who is not shown to be under disability of mind, is presumed to intend the natural and normal consequences of his acts and conduct. State v. Ramsay, supra. Nothing else appearing, the defendant’s motive for doing wil-fully an act forbidden by statute is no defense to the charge of violation of such statute. Cox v. Louisiana, 379 U.S. 559, 85 S. Ct. 476, *15513 L. Ed. 2d 487; Commonwealth v. Anderson, 272 Mass. 100, 172 N.E. 114, 69 A.L.R. 1097; 21 Am. Jur. 2d, Criminal Law, § 85.
Each warrant in the present case charges the defendant named therein in plain and precise language with each element of this statutory offense at the specified time and place by the specified conduct of picketing in front of the school, which picketing interfered with classes at the school. Each warrant is sufficiently specific to protect the defendant named therein from being placed again in jeopardy for the same offense. Consequently, the motion to quash the warrants was properly overruled unless the defendants had, as they contend they did have, a lawful right to engage in the specified conduct, notwithstanding the statute.
The uncontradicted evidence of the State, if true, as it must be deemed to be in passing upon a motion for judgment of nonsuit, is sufficient to show that the defendants, other than Frinks, intentionally paraded back and forth in front of the specified public school building and grounds in the immediate vicinity of a class then in progress on the school grounds. The evidence likewise shows that Frinks intentionally aided, abetted, directed and counseled the marching. The marchers carried placards or signs. These signs were utterly meaningless except on the assumption that they related to some controversy between the defendants and the administration of the school, specifically Principal Singleton. Presumably, they were deemed by the defendants sufficient to convey some idea to students or teachers in the school. The site was the edge of a rural road running in front of the school grounds, with only two residences in the vicinity. There is nothing to indicate that the marchers intended or desired to communicate any idea whatsoever to travelers along the highway, or to any person other than students and teachers in the Southwestern High School. As a direct result of their activities, the work of the class in bricklaying was terminated because the teacher could not retain the attention of his students, and disorder was created in the classrooms and hallways of the school building itself. Consequently, the motion for nonsuit was properly overruled nnleps the defendants had, as they contend, the lawful right so to interrupt and disturb this public school, notwithstanding the provisions of the statute.
The contention of the defendants that the court committed error in admitting evidence as to the conduct of the students in the bricklaying class and in the school building in response to the marching of the defendants must be deemed frivolous. An essential element of the offense charged in the warrants is the actual interruption and disturbance of the program of the school. Obviously, this can be shown only by evidence of the effect of the defendants’ conduct upon *156the activities of the teachers and students of the school. The witnesses, who testified concerning this, related their own observations of what happened upon the school grounds and within the school building while the conduct of the defendants was in progress, as contrasted with the good order which prevailed prior to the commencement of the marching and after the departure of the defendants. Such evidence was clearly material and competent.
When the defendants challenged the array of regular jurors summoned for the term, on the ground of unconstitutional discrimination against members of their race in the selection of names to go into the jury box from which the panel was drawn, the trial judge conducted a hearing and heard all of their evidence upon that matter. Upon this evidence, he found that a ■ disproportionately small number of names of Negroes had been included in the box. He thereupon ordered that no member of the regular jury panel be called as a juror for the trial of these cases and directed the sheriff to summon a special venire of fifty persons “without regard to race.” This was done and from that panel the jury which tried and convicted the defendants was chosen, six of those jurors being Negroes. The contention of the defendants that it was error to order such special venire is without merit. The procedure so followed by the trial judge is expressly authorized by G.S. 9-11, and the contention of the defendants that tales jurors can be called only to supplement an insufficient number of regular jurors is refuted by the very case they cite in their own brief, State v. Manship, 174 N.C. 798, 94 S.E. 2, in which this Court, speaking through Clark, C.J., said:
“It has never been controverted that the judge in his discretion has the power to excuse any juror and to discharge any jury that he thinks proper. It seems that in this case the regular jury had been discharged under the impression that the business of the court was over. This case coming up, the defendant asked for a continuance. But, there being no other ground suggested therefor, the court, in the exercise of its discretion, directed tales jurors to be summoned, under the above statute [G.S. 9-11], which was passed for this very purpose, that 'there may not be a defect of jurors.’ There was long a practice, under the former statute, that the judge should reserve one juror of the regular panel to ‘build to,’ based upon the technical idea that the tales jurors should be other jurors, as if they would not be ‘other’ jurors even if that one juror had also been discharged. It was no prejudice to this defendant that one regular juror was not retained. Twelve jurors, freeholders, to whom he entered no exception, sat upon his case, and he was duly convicted.”
*157There is nothing in this record to indicate that any juror who sat upon the case and convicted the defendants was challenged by any of the defendants. The record does show that the defendant Wiggins, having exhausted her peremptory challenges, attempted to challenge peremptorily a seventh juror and her challenge to that juror was disallowed. However, the record shows that the juror so challenged by her was removed from the jury upon the peremptory challenge of another defendant.
The record does not indicate that any other case was tried at this term of court or that any regular juror, or any other juror drawn from the jury box, participated in any way whatever in any proceeding before the court at this term or at any other term. The objection of these defendants to trial by jurors drawn from the jury box having been sustained, and they having been tried by a jury summoned and selected pursuant to the statute, and without discrimination on account of race or otherwise, the defendants may not attack the judgment entered against them because of a defect in the composition of the jury box from which the regular panel was drawn.
We have no information as to what action has or has not been taken with reference to the jury box since the trial of these cases, and that question is not now before us.
The special venire was not rendered invalid by reason of the fact that the sheriff who summoned it, pursuant to the orders of the court, was a witness for the State in these cases. State v. Yoes, 271 N.C. 616, 157 S.E. 2d 386; Noonan v. State, 117 Neb. 520, 221 N.W. 434, 60 A.L.R. 1118; 31 Am. Jur., Jury § 108; Anderson on Sheriffs, § 280.
We are, therefore, brought to the principal contention of the defendants, which, in effect, is that they had a lawful right wilfully to interrupt and disturb the operation of this public school for the reason that they were carrying signs bearing the above quoted words thereon, and the purpose of their marching was to convey to someone (obviously, students or teachers in the school) some idea. That is, the defendants assert that the Constitution of this State, Article 1, § 17, and the Fourteenth Amendment to the Constitution of the United States, permit them, with immunity from prosecution, to disrupt the operation of a public school so long as the means used by them for that purpose is marching back and forth in front of the school while carrying banners and placards on which words appear.
Freedom of speech and protest against the administration of public affairs, including public schools, is a fundamental right which has been cherished in this State since long before the adoption of the Fourteenth Amendment to the United States Constitution. It has, however, never been doubted that this is not an absolute freedom or *158that the State, in the protection of the freedom of others and of its own paramount interests, such as its interest in the education of its children, may impose reasonable restraints of time and place upon the exercise of both speech and movement. Thus, in State v. Ramsay, supra, a former member of a religious congregation, who had been expelled therefrom for reasons or pursuant to a procedure which he deemed insufficient and unjust, was convicted and punished for disturbing public worship when he persisted in breaking into a worship service of the church and rearguing the supposed merits of his case. Neither the enactment of G.S. 14-273 nor its enforcement against these defendants in this case violated the Law of the Land Clause of Article I, § 17, of the Constitution of North Carolina.
The Fourteenth Amendment to the Constitution of the United States grants to the defendants no license wilfully to disturb the operation of a public or private school in this State.
G.S. 14-273 is not discriminatory upon its face. It is universal in its application. Anyone who does that which is prohibited by the statute is subject to its penalty. It does not confer upon an administrative official the authority to issue, in his discretion, permits to disturb public schools and, therefore, does not invite or permit that type of administrative discrimination against the disseminators of unpopular ideas which was condemned in Saia v. New York, 334 U.S. 558, 68 S. Ct. 1148, 92 L. Ed. 1574.
Neither the statute nor its application in this case has the slightest relation to State approval or disapproval of the ideas expressed on the signs carried by the defendants, or of the position taken by the defendants in their controversy, whatever it may have been, with the principal of the school. Like the ordinance involved in Kovacs v. Cooper, supra, this statute does not undertake censorship of speech or protest. As the Court said in the Kovacs case: “City streets are recognized as a normal place for the exchange of ideas by speech or paper. But this does not mean the freedom is beyond all control.” Again in Schneider v. State, 308 U.S. 147, 60 S. Ct. 146, 84 L. Ed. 155, the Court, recognizing the authority of a municipality, as trustee for the public, to keep its streets open and available for the movement of people and property, said, by way of illustration, a person could not exercise his liberty of speech “by taking his stand in the middle of a crowded street, contrary to traffic regulations, and maintain his position to the stoppage of all traffic * * *” G.S. 14-273 does not have “the objectionable quality of vagueness and overbreadth” thought by the United States Supreme Court to render void the Virginia statue under examination in NAACP v. Button, 371 U.S. 415, 83 S. Ct. 328, 9 L. Ed. 2d 405. G.S. 14-273 is not “susceptible of sweeping and improper application” so as to pre*159vent the advocacy of unpopular ideas and criticisms of public schools or public officials.
Unquestionably, “the hours and place of public discussion can be controlled” by the State in the protection of its legitimate and vital public interest in the efficient operation of schools, public or private. See Saia v. New York, supra; Kovacs v. Cooper, supra. The classic statement by Mr. Justice Holmes in Schenck v. United States, 249 U.S. 47, 39 S. Ct. 247, 63 L. Ed. 470, “The most stringent protection of free speech would not protect a man in falsely shouting fire in a theatre and causing a panic,” is still regarded by the Supreme Court of the United States as a correct interpretation of the First Amendment. The education of children in schools, public or private, is a matter of major importance to the State, at least as significant as the free flow of traffic upon a city street.
In Cox v. Louisiana, supra, the Court recognized that picketing and parading are subject to state regulation, even though intertwined with expression and association. There, the Court, quoting from Giboney v. Empire Storage & Ice Co., 336 U.S. 490, 69 S. Ct. 684, 93 L. Ed. 834, said, “[I]t has never been deemed an abridgment of freedom of speech or press to make a course of conduct illegal merely because the conduct was in part initiated, evidenced, or carried out by means of language, either spoken, written or printed. Accordingly, the Court there held valid on its face a state statute prohibiting picketing and parading in or near a building housing a state court, with the intent of obstructing or impeding the administration of justice. The Court said, “Placards used as an essential and inseparable part of a grave offense against an important public law cannot immunize that unlawful conduct from State control.” It deemed “irrelevant” the fact that “by their lights,” the marchers in that case were seeking justice. Similarly, it is irrelevant here that the defendants may have been “by their lights” seeking the improvement of the educational processes at Southwestern High School. Whatever their motives, the result of their wilful activities was the disruption of those processes at that school. That is what the statute forbids and, in so doing, it does not violate limitations imposed upon the State by the First Amendment to the Constitution of the United States, now deemed by the Supreme Court of the United States to be made applicable to the states by the Fourteenth Amendment.
It is also irrelevant that the defendants marched silently, were not on the school grounds, and neither threatened nor provoked violence. Their actions can admit of no interpretation other than that they were planned and carried out for the sole purpose of attracting and holding the attention of students or teachers in the South*160western High School at a time when the program of the school required those students and teachers to be engaged in its instructional and training activities. There can also be no doubt that they succeeded in this purpose. The uncontradicted evidence as to the defendant Frinks is that, before the marching began, this statute was called to his attention and explained to him in substance, to which he replied, “I don’t care anything about what is in the Statute Books.” In the light of the uncontradicted evidence, the sentences imposed by the presiding judge were lenient.
As the Supreme Court of the United States said in Cox v. Louisiana, supra, “There is a proper time and place for even the most peaceful protest and a plain duty and responsibility on the part of all citizens to obey all valid laws and regulations.” The defendants wilfully ignored this elementary principle of sound government under the Constitution of our country.
We have carefully examined each assignment of error and the authorities cited by the defendants in their brief. We find nothing in the statute, or in the proceedings in the court below, which entitles the defendants to a new trial or to the reversal or arrest of the judgments of the court below.
No error.
