A friend of mine was arrested about a month ago. He pulled into a gas station and an unmarked car pulled in behind him, an undercover policeman got out and came at him with a taser gun. He had not tried to run from the police. He was cuffed and put into the back of the police car. When he was searched there was nothing found on his person. The girl he was with was also searched and had possesion of paraphenalia. At that time they searched his car and they searched the trunk. In the trunk they found cocaine. All this took place while he was in the back of the police car. Is it an illegal search of the trunk if he was not able to see the officers conducting the search?
