I don't mean to be Devil's Advocate but....
You know how many punks, druggies, pusher, pimps, ho ho's, guns, drugs etc. have been caught because "The driver looked suspicious"?
I'm sorry but If I were a cop and I saw a car full of kids dressed like gang members about to do a drive-by I'd pull them just to see what's what. But you can't just pull them for no reason.
I've been on MANY ride-a-longs and 99% of the time if they look crooked, they are. They just follow and wait and sooner or later they will do something stupid enough to get pulled over. The crooked ones are usually the ones that try to play roadside lawer, give attitude, and end up getting arrested and their car impounded.
Trust me, in this day and age, if the police feel uncomfortable they WILL cuff and stuff you first, THEN find out what is going on.
I can't count the number ot times I've heard "This guy has a burned out tail light, I'll pull him just to let him know to get it fixed." I'd ask if he was going to run the plates..."Nope, no reason. Just let the guy know his light is out." But the punk gave soo much attitude he gives the cop a reason to get suspicious and ask more and more questions like "where are you going? where you been? Why?"can I see your registration and D/L? Bingo! They guy just beat up some one with a baseball bat (that was in the back seat) across town.
If the guy would have just said, "Thanks, I'll go to Napa tomorrow and get a new one." He would have been free and clear.
Don't get me wrong, Pulling a guy because he's some sort of race other than white is absoultely WRONG! Pulling someone over for no reason is WRONG!
But, If it looks like a duck, and quacks like a duck. There's a pretty good chance it's NOT a kitten.
