I think I've told this story before, but it's a good one. A friend got pulled over one night because the red tape on his broken tail light was faded. Knowing it was a BS stop, but also not really knowing his rights and knowing he had nothing to hide, he let the cop search. His car was a complete mess. Everything was going fine until the cop found his oil checking rag, which happened to be an old pair of whitey tighties, with dark brown oil streaks all over it. The cop flipped out, told him he was disgusting, and let him go. He also happened to drop his police issue Smith & Wesson switch blade knife in Quinn's car, which he later gave to me for fixing his tire.
One time I was driving my ambulance (with all the race crap in it) to work at a government facility. After going through the gate I saw they were pulling over random cars to search. One of the base cops that I know was standing in the road getting ready to pick out another car so I stopped beside him and asked if he wanted to search my ambulance. He just laughed and said "no, it would take too long and I didn't pack a lunch".
I got pulled over after getting lost in a little neighborhood. I had just bought a retracting air hose real and had it in the back of my truck. A pesky porker in a undercover Vic started following me. I was lost and the streets are blocked of so you cannot just drive out of the neighborhood. Well as soon as I find my way out I get hit with the blue and whites. The guy asks me what I'm up to and I explain buying the hose reel. He asks about how much I paid, did I steal it, etc. The damn thing must weigh 25-30 pounds and I had to help the seller take it down by holding it up so I was a bit sweaty. Not the type of high value stuff I'd steal if I was a thief. The guy basically gave me 20 questions and mentions there have been a bunch of burglaries in the neighborhood. After he figures I'm honest he mentions, "oh and you have to put your turn signals on 100ft before turning." I had used my signals but couldn't figure the easiest way out so I guess getting lost is a suspicious activity. If getting lost was illegal I'd be in jail!
If you really want to throw the K9 off put some road kill scent on your car or cat piss. Dogs have a one tract mind and if you tap into their natural preferences they cannot think about drugs, guns, etc. a piece of dead meat is all a dog really wants.
