U do know most headshops are being watched by the po's. I know this becuz my buddy bought a bong at a headshop and left, minutes later the police pulled up,searched him and arrested him, becuz he had buds. this happens to alot of people everywhere, its just cuz them piggys are nosey bastards.
That sucks man. I think he would have the right to say no to the cops searching his car though because he just bought a brand new piece or something....unused...no signs of resin or anything. Thats bullshit.
