Can a prosecution cross-examine a psychiatric expert more extensively and searchingly than a lay witness?

A party "may cross-examine an expert witness more extensively and searchingly than a lay witness, and the prosecution was entitled to attempt to discredit the expert's opinion. [Citation.] In cross-examining a psychiatric expert witness, the prosecutor's good faith questions are proper even when they are, of necessity, based on facts not in evidence. [Citation.]" (People v. Dennis, supra, 17 Cal.4th at p. 519, 71 Cal.Rptr.2d 680, 950 P.2d 1035.)
