My 19 yr old son was driving w/a girlfriend in the car @ approx 5:00 PM. Cops stopped them for no reason (no traffic summons issued or reason for stop given). Supposedly there was a "grinder" laying on the backseat (again, supposedly belonging to a friend , who had been in the car the previous night). The grinder had some maijuana residue or small amount (?) in it. Cop was instructed by the 2nd officer as to how to write out a desk appearance tkt for marijuana possesion. From my son's brief description, it sounded as if this issuing officer was a new rookie and was being broken in by the other more experienced officer - were they making a practice/training traffic stop? Question: Did they have a legal right to stop him if no traffic infractions were committed and does the subsequent seizure of this "grinder" constitute "illegal search & seizure". Does he stand a good chance of beating this thing or is he wasting his time?
