Defendant's suppression motion was properly denied. The People met their burden of proving beyond a reasonable doubt that under the totality of the circumstances, defendant's statements were knowingly, intelligently and voluntarily made (see, People v. Anderson, 42 N.Y.2d 35). The burden of showing the validity of the police conduct in the first instance was on the People and once the lawfulness of that conduct was established, the burden of persuasion shifted to defendant to show that he was not mentally competent to voluntarily waive his rights (People v. Love, 57 N.Y.2d 998). The evidence did not establish that defendant's mental condition was such as to cast doubt on the voluntariness of his statements (see, People v. Williams, 62 N.Y.2d 285), or on their reliability (see, People v. Schompert, 19 N.Y.2d 300, cert denied 384 U.S. 874).
The court properly exercised its discretion in precluding the defense from presenting expert testimony with respect to his justification defense. Under the circumstances of the case, whether defendant acted in self-defense was within the ken of the typical juror (see, People v. Robles, 173 A.D.2d 337, lv denied, 78 N.Y.2d 1014). The psychiatric evidence was offered to show that defendant's belief that the victim was about to rob defendant of his (imaginary) hoard of valuable jewelry was a delusion. While psychiatric evidence may in some cases be relevant to the subjective component of the justification defense (see, People v. Goetz, 68 N.Y.2d 96, 114), in this case the proffered testimony would only have been relevant to an insanity defense. However, defendant expressly waived that defense.
We perceive no basis for reduction of sentence.
