2010As County Court is not obliged to assist defendant in “an unrestrained ‘tour of investigation seeking generally useful information’ ” that lies outside the bounds of the Rosario rule, we would reject defendant’s Rosario argument and address his remaining claims of error (People v Poole, 48 NY2d 144, 148 [1979], quoting People v Rosario, 9 NY2d at 290 ).

2000After conducting a sufficient inquiry of the prosecutor and a police witness, the court properly exercised its discretion in declining to examine the officer’s notes to determine whether they suggested that other notes had been prepared by the officer that were not turned over to the defense in violation of the Rosario rule (see, People v Poole, 48 NY2d 144 ).

2025Because defendant fails to establish any Brady or Rosario violation, his contention that counsel's failure to pursue such claims constituted ineffective assistance of counsel is unavailing ( see Strickland v Washington , 466 US 668 [1984]; People v Benevento , 91 NY2d 708 [1998]; People v Baldi , 54 NY2d 137 [1981]).

2000(People v Baldi, supra, at 147 ; People v Benevento, 91 NY2d 708, 713 [1998].)
