Why do people screw with cops? I never understand it. It always ends the same. The cops have the power. If they feel threatened they have the authority to use that power.
Repeat after me: "Yes officer. No officer. What do I need to do to take care of this officer? I'm afraid I don't understand, could you please explain what you'd like me to do officer?"
Think Eddie Haskel.....ESPECIALLY if you are doing something wrong. Are you tripping with a baggie in your pocket and a gun in the glovebox? The last thing in the world you want to do is give the cop probable cause to search you. Just chill out, let the cop do his job and get on with your life.
