The opinion of an expert is not admissible to prove a matter of common experience and knowledge, upon which any person of ordinary intelligence is capable of arriving at a correct conclusion, i Wharton, Ev., sec. 436; Milwaukee, etc., R. Co. v. Kellogg,
The provision of our criminal code embraced in section IS51 is doubtless an outgrowth of the doctrine on which these rules were founded. The right, however, to use such force as is necessary to prevent a mere intrusion into a dwelling house exists independently of that section of the statute. And the attempt to effect such intrusion may be resisted, without regard to the intent with which it is made or the manner of making it. But section 1551 applies only where the attempt is made in the manner and for the purpose which it mentions. And even where the attempt is thus made, a homicide committed in resisting it will not be excused if done unnecessarily. (Mansf. Dig., sec. 1526). To make such a homicide justifiable when committed as a means of self defense, it must reasonably appear to the person committing it that the entry of his assailant into the biouse will expose him to the danger of losing his life or of receiving a great bodily injury. And it is his duty to prevent the entry by means not fatal if he can do so consistently with his own safety. Pond v. People,
Brown had the same right of defense in Mrs. Ratliff’s house that he would have had in his own. Whether the deceased was attempting to enter it and in what manner and for what purpose, and whether at the time he was killed the life of Brown was imperilled or his person exposed to the danger of great harm, were all questions for the jury under proper instructions as to the law. The several sections of the digest defining justifiable homicide are parts of the same statute, and so close is their relation that each to some extent explains or controls the meaning of the other. It was proper to give them all in charge to the jury, together with the sections defining murder and voluntary manslaughter. The defendant was also entitled to an instruction making a practical application cf the law to the facts which the evidence on his part tended to establish. As a charge for that purpose his second request would not have been more favorable to his theory of the case than it was proper to give if, after its recital of facts, it had concluded by saying that the killing was justifiable if the defendant reasonably believed it was necessary to prevent the deceased from entering the house. But the modification made by the court obscured the meaning of the charge and rendered it inappropriate to the defense on which it was requested.
By the first clause of the court’s second instruction the jury were told that to justify the defendant in killing the deceased “ he must have acted under an honest belief that it was necessary at the time of the killing to take the life of the deceased in order to save his own life; ” and it is not stated in any part of that instruction that the homicide was also justifiable if it was committed in necessary sfelf-defense and to prevent a great bodily injury. This omission did not occur in the first instruction, and we presume it escaped the presiding judge’s notice. But it made the instruction incomplete as a separate and distinct declaration of the law. And it appears from the bill of exceptions that the prosecuting attorney in his argument to the jury insisted that under the charge they had received the defendant could not justify the killing if he could have saved his life by flight. The use thus made of the instruction is assigned as a ground of the motion for a new trial. But it is shown that the attention of the court was not directed to it at the time the argument was made. If attention was called to the error at any time before the verdict was rendered, it was the duty of the court to correct it.
There was no error in refusing the defendant’s first instruction. The fourth instruction he requested was a correct statement of the law on the subject to which it relates and was improperly refused. But the points it embraced were perhaps substantially covered by a clause in the court’s second instruction.
It does not certainly appear from the record whether the other threats excluded were sufficiently recent to make them also admissible. See 2 Bish., Cr. Pro., sec. 621.
The admission of Dr. Kirkscey’s testimony' mentioned in the brief of counsel was not complained of in the application for a new trial.
It is not important to consider the other questions presented by the defendant’s exceptions.
For the errors pointed out the judgment is reversed, and the cause is remanded for a new trial.
