In People v. Hurley (1979) 95 Cal.App.3d 895, appellant, through appointed counsel, moved for the appointment of an eyewitness identification expert. In his supporting papers, he merely indicated that the expert was "crucial evidence" in the case and was required to examine the prosecutor's evidence and perhaps to testify. The Hurley court said at page 899: "We are of the opinion that such a weak showing in the trial court in this case is very similar to that made in the trial court in Collins v. Superior Court (1977) 74 Cal.App.3d 47, 52 where the court noted: '. . . Petitioners made no showing whatsoever, other than the bare assertion, that an expert was needed to evaluate information communicated from petitioners. The court could reasonably conclude no expert was needed for this purpose.' "
