I was arrested at a location known as an "open air drug market." The police raided the place while I was there and I was found to have drugs on me. I was only charged with possession, but the police didn’t arrest the man who sold them to me. What is going on? Why didn’t he get arrested?
It could be as simple as the fact that they didn’t see the actual sale. It could also be because he is a cooperating individual who is working with the police. He could also be an undercover policeman who will turn up at your trial to testify that you bought it from him in the event that you claim the drugs were planted or raise some other defense. In any event the fact that he was not arrested doesn’t really help you much. If they missed the sale, it is just how it worked out. If he was an undercover cop you will have a difficult time raising an entrapment defense because you were in a drug market.
