but if you're not doing anything wrong you shouldn't worry.
That phrase right there is one of the biggest crocks of crap ever uttered. Innocent people are hassled for no good reason every day. Maybe you enjoy spending quantity time with Barney on the side of a crowded highway because you have an NRA sticker on your car and having him paw through your stuff just because of the sticker. Not every one does.
(Remember the Right wing "Terrorist" advisory issued earlier in the year)
And no I am not anti-cop. I've done my time in a patrol car. I am anti abuse of power and the principle of guilty until proven innocent.
