Is there any case law in which the police have been found to have played on a suspect's religious beliefs?

The majority are evidently of the opposite view. To be sure, they agree that the police may not play on religious beliefs, stating that "the tactic of exploiting a suspect's religious anxieties has been justly condemned" and citing to People v. Adams, supra, 143 Cal.App.3d 970, 192 Cal.Rptr. 290. (Maj. opn., ante, at p. 173 of 275 Cal.Rptr., at p. 529 of 800 P.2d.) But they disagree that the officers in this case acted improperly: "none of the police comments here appear to have been calculated to exploit a particular psychological vulnerability of defendant; no acute religious anxiety or sense of guilt was apparent from prior questioning...." (Id. at p. 173 of 275 Cal.Rptr., at p. 529 of 800 P.2d.) Perhaps no religious sensitivity was evident earlier in the interrogation. But it plainly became evident in its course. And as soon as it did, it was purposely exploited.
