S, a university student, ran a red light and was stopped by the police. He was asked to get out of his car and was questioned about why he ran a red light and was speeding. S gave unsatisfactory answers. The police looked around the car and saw a suspicious package. They asked if they could open it; S said yes. The package turned out to contain drugs. The police asked S for the source of the drugs. S said he got it from his dormitory roommate. The police then went to S’s room and found more drugs. During the trial, S claimed he should have been given the Miranda warnings by the police.
Based on the officer’s failure to give the Miranda warnings, are any of the drugs confiscated admissible in evidence? Justify your answer.
