In a full-fledged opinion by Judge Rivera, the Court of Appeals affirmed the conviction of a psychiatric patient based on his assault of another patient. The court determined the doctor, who was cross-examined about defendant’s capacity by defense counsel, could have been questioned by defense counsel about the hearsay basis for her opinion. The failure to do so could not be complained about on appeal. The court also determined an objection to a line of questioning did not preserve the issue of witness-bias for review because defense counsel’s proffer did not specifically mention the exploration of witness-bias as the purpose of the questioning.
