Approx 10 pm. My son 16 was sitting is a car with 2 other friends talking. The driver had temporarily parked in the parking lot of our local funeral home because they had missed the driveway to another friends house that was just before it. So, my son and another friend of his walked up to the driver in the car (a mutual friend) and they got in and started talking for a couple of minutes, and then they got out. The police pulled up, asked them what they were doing..the driver explained he had missed the driveway..and they they were all just talking..the police searched the vehicle and each one of the kids. The driver had drug paraphernalia (pipe) on his person (concealed), the other kid had an empty "roach" paper in his duffle bag, but my son had nothing on him and was charged. Legal?
