Heading: Officer Thompson's Testimony

Text: Officer Thompson testified for the People during the penalty phase concerning his investigation of the Glashien and Blundell killings. He recounted defendant's confession to those crimes as well as defendant's vague statements concerning other murders he purportedly committed in Las Vegas. On cross-examination, Thompson admitted that he doubted the veracity of defendant's confession to the Las Vegas killings, and he observed that no law enforcement officers contacted by him credited it. On redirect, Thompson stated his further belief that defendant's confession to the Glashien and Blundell killings, being supported by sufficient details, was true. Defendant did not object to the foregoing testimony. (23) Defendant now observes that a police officer's opinion regarding the truthfulness of a suspect's confession is generally deemed inadmissible. (See People v. Cole (1956) 47 Cal.2d 99, 103 [301 P.2d 854, 56 A.L.R.2d 1435]; People v. Arguello (1966) 244 Cal. App.2d 413, 421 [53 Cal. Rptr. 245].) His failure to object, however, bars our consideration of the point on appeal. (See, e.g., People v. Coleman, supra, 46 Cal.3d 749, 777-778.)
