There's a video floating around the Internets at the moment. Here's a summary:
Idiots A and B are sitting in their car. Idiot A is filming Idiot B, daring him to go over to a nearby police officer and tell him to fuck off. "Seriously -- what can he do to you? What can he do?" Sufficiently persuaded, Idiot B gets out of the car and, still being filmed by Idiot A, walks up to the cop and repeatedly flips him off. The cop then pulls out his nightstick and starts clubbing the fuck out of Idiot B. Idiot A: "Oh shit! Fuck!"
This video serves as the ultimate illustration of two other things I've read recently: the first is this reminder from Psycho Milt about how cops in other countries don't take your shit; the other is this older one from Hewligan, where he points out that it's possible for both sides in a given dispute to be equally as wrong.
See, a lot of people would say "the guy's an idiot, he deserved what he got, good on the cop" (I know this, because that's exactly what they said about the Annoying Woman Gets Tasered All To Fuck For Talking On Her Cellphone video of a while ago). But you don't have to take sides -- the guys are chuckling morons and the cop is a dangerous psychopath. No-one in that video is in the right.
The logical ramifications of accepting that such a situation is possible in a rational ethical system are doubtless fodder for a fruitful and intelligent debate, but instead, here's a Snopes article about the true dangers of frozen squirrels.
