Jones Accord, Mag.R. at 5-6; see note 3 supra. 6 In this regard, it is significant to note that while probative evidence casting doubt on a witness’ mental stability at the time of the incident about which he testifies may, of course, be used to discredit him, see United States v. McFarland, 371 F.2d 701, 705 (2d Cir.1966), cert. denied, 387 U.S. 906 , 87 S.Ct. 1689 , 18 L.Ed.2d 624 (1967); see also United States v. Hiss, 88 F.Supp. 559 (S.D.N.Y.1950), not all psychiatric reports about prosecution witnesses are sufficiently probative to require disclosure and/or free use in cross-examination.
