Does the prosecution erred in not turning over the evidence presented at trial?

Even assuming the prosecution erred in not turning over the evidence, we agree with the People that it was not prejudicial in light of the fact that none of it was presented at trial by the defense, a telling indication that it was not exculpatory and did not lead to other exculpatory evidence, despite the continuance granted by the trial and agreed to by the defense. As the People assert, defendant's guilty conviction makes it clear beyond a reasonable doubt under the standard of Chapman v. California (1967) 386 U.S. 18, 24, that there was probable cause to hold defendant to answer the charges against him.
