People! Please stop slamming on your brakes when you see a cop that has pulled somebody over!!! Unless your are holding a severed head out the window, he's too busy for you!
And even if you are holding a severed head out the window, slamming your brakes might make you drop it and then you'll have to pull over and get out and look for it since it'll probably roll away and it just turns into a whole THING.
