Just tell the police officer to read your sig, he'll understand


But seriously, i believe that you're telling the truth, but somebody is just messing with you. If he didn't arrest you when you gave him the money, they dont fucking call you and tell you whats going down, and then arrest you that night, somebody is pulling your leg. Somebody who knows that you're buying pot tonight, so i say go and pick up your pot and it'll all be good.
