IF Pennsylvania allows tinted windows to be a primary reason for a stop (probably isn't due to the "oh, and you have a headlight out" charge), then it was a legal stop. And findings incidental to legal stops are admissable, so if the cop found drugs or such, then it would be admissable.
But look at Buc's argument that "being upset often equals illegal activity". THIS IS THE PROBLEM BUC. It's like saying "being Black often equals illegal activity", or "driving through this part of town often equals illegal activity". "Often equals illegal activity" does NOT give police the right to harass law abiding citizens.
Maybe if cops would stop being such dickwads they would get more public support, and we would be able to work TOGETHER to get tough on REAL crime.
Think about it. This occurred in Philly....not exactly a town known for it's safe streets. This stop took a street cop off of the beat for at least 15 minutes. Meanwhile I'm sure there were people getting robbed/mugged/raped/murdered in that city....but the cop is busy arguing about (legal) tinted windows.
I"m all for cops pulling people over for (real) petty lawbreaking because, like Giuliani said, if you take care of the small things the bigger things take care of themselves. But this driver did everything RIGHT - opened up the back window so the cop could see in, kept his hands out front, etc....should've looked at the tinted window exemption and let him go on.
