Charles Foreman and Homer Deal have appealed from convictions based upon evidence that they stole a hog from Albert Taylor. Twenty-nine errors are assigned. Only the ninth will be discussed— that the court erred in allowing the prosecuting attorney, over objections of the defendants, to ask Sheriff W. C. Cruce if actions and conduct of the. defendants did not lead the witness to believe they were guilty.
On cross-examination the officer was questioned 'by C. T. Sims, counsel for the defendants, relative to the conduct of the defendant Deal after Deal knew that he was suspected. The prosecuting witness (Albert Taylor) had testified that he found his hog in the defendant Foreman’s barn. Foreman and Deal are brothers-in-law. Thereafter, Sheriff Cruce was told by Taylor that the hog was in Deal’s barn.1 Cruce went to the barn and was told by Foreman that a black boar then in the bam belonged to Deal, and that Deal got it from Claude Wolf. Deal testified he got the hog from Curtis Funderburg, in *890Bradley county. Funderburg supported Deal’s statement. Shortly after. Taylor inspected the hog in the Foreman barn, it disappeared, and was not thereafter seen.
During the cross-examination of Sheriff Cruce it was brought out that the officer had asked Deal to come to his office for questioning. The interview was delayed on account of the illness and subsequent death of Deal’s daughter. Cruce testified that after the child’s condition became acute he did not expect Deal to come at once. The officer further testified that after the first conversation he had with Deal, the latter did not make any effort to avoid him.
Up to this point cross-examination of Cruce was directed in part to matters relating to the conduct of Deal. Counsel for appellants then asked the officer if he found Funderburg and Deal together in Warren, to which there was an affirmative reply. Cruce stated that he had no way of knowing what the two were talking about. Following are some of the questions and answers as shown by the trial transcript:
££Q. There wasn’t anything of your own knowledge that would 'cause you to draw the conclusion that the discussion was on hogs, was there? A. Nothing—except under the circumstances.
££Q. A mere conjecture in your mind? A. A kind of conclusion arrived at from past experiences and facts.
££Q. What we call, under the rules of evidence,- an improper conclusion of a witness? A. It might be.”
On redirect examination, conducted by the prosecuting attorney, there is the following:
“Q. Mr.' Sims [counsel for the defendants] just said, £. . . by your past experience.’ What past experience have you had in investigating this kind of a case ? A. I have investigated a number of them.
££Q. Did the defendants’ [actions] and conduct lead you to believe that they were guilty? (Objections overruled and exceptions saved.) A. Yes.”
*891It is urged by tbe state that the sheriff testified as an expert, and therefore the rule against opinion evidence does not apply. On behalf of the Attorney General it is said: “Certainly if a man can become an expert as to the operation of an automobile by working with it so as to be allowed to testify as an expert witness on the speed of it, a sheriff of a county, who makes many criminal investigations, would be an expert in matters of criminology, and should be allowed to testify as an expert.”
While it is true that the modern conception of the admissibility of evidence is that it is more important to get the truth than to quibble over impractical distinctions between facts and concluso'ns,2 and there are limitations to the rule which excludes opinion testimony, none of the exceptions goes to the extent of permitting an arresting officer to testify that the conduct of a defendant caused him to believe that the defendant was guilty.
Expert witnesses who have skill, learning, or experience in a particular, science, art, or trade (and criminology is not to be excluded from the sciences), may give an opinion in a proper ease upon a given state of facts relating thereto. It has also been found necessary to admit a class of evidence from nonexpert witnesses, which is usually spoken of as “opinion evidence,” where the facts as they appear to the witness cannot clearly and adequately be reproduced, described, and detailed to the jury.3
The record in the instant case is sufficient to show that Sheriff Cruce is a most efficient and capable officer, with considerable experience in dealing with criminal matters; and, while his answer to the objectionable question is unquestionably his honest conclusion, it is, nevertheless, a conclusion, and it is predicated upon facts and circumstances which are not shown to stem from scientific investigation, the nature of which could not be adequately explained to the jury. For example, had the of*892ficer been called upon, in tbe light of his experience with firearms . and his knowledge of chemistry, to testify whether, in his opinion, discolorations were caused by powder-burns or by blood-stains, there could have been no tenable objection, provided the proper foundation had been laid; and he might testify that in his opinion a certain wound was caused by a bullet, or a knife, or other instrumentality. But he would not be permitted to testify to the facts and state his conclusions, and then give an opinion as to the guilt or innocence of a defendant. That determination is for the jury.
At page 643 of 20 American Jurisprudence, § 771, there is an excellent text entitled “'Conclusions Distinguished from Facts—Composite Facts.” There it is said: ‘ ‘ The general rule excluding opinions of witnesses is sim: ■pie in its statement, but not so simple in application, for it is not always easy to distinguish in the testimony of a witness facts within his knowledge or observations from his opinion on facts. As a general rule a witness may testify to a composite fact, although in a sense his testimony may include his conclusion from other facts. In the multitudinous affairs of everyday life, it is extremely difficult to distinguish between ‘ opinion ’ on the one hand, and ‘fact’ or ‘knowledge’ on the other. Moreover, objections that proposed testimony states a conclusion are sometimes pushed to captious extremes.
“The true solution seems to be that such questions are left for the practical discretion of the trial court. Often the simplest and most satisfactory method is to permit a witness to state a fact as he knows it and leave the ground of his belief to be developed by cross-examination. In such cases it is within the- administrative discretion of the court to require the witness’s observations and particulars of examination to be more fully set forth or to allow his testimony to stand, leaving the parties to examine and cross-examine him with respect to the same.”4
*893It is next insisted on behalf of the Attorney General that “. . . if the question was erroneous, which we do not concede, it was invited error, as the court can see by checking the concluding part of the cross-examination of the attorney for appellants on page 50 of the transcript. ’ ’
It will be seen that in the first conversation referred to the sheriff was asked if he knew what Deal and Fun-, derburg were talking about. In the second instance, the sheriff was required to say whether he thought Deal and Foreman were guilty.
For the error in admitting the opinion testimony of Sheriff Cruce, the judgments are reversed. The causes are remanded with directions to retry.
