Here's some disturbing video, allegedly shot in Russia some time last week, of a polar bear attacking a woman in a back alley. The bear — and how it got there remains a mystery even Damon Lindelof would be hard-pressed to explain — then flees, possibly because a horrified onlooker threw something at it. Then, shockingly, the woman stands up and walks away, her torn pants dangling around her ankles. (This image has led some anonymous online analysts to suggest she was peeing at the time of the attack, which is idiotic.) That last part makes the first part tolerable, but be warned: Seeing a bear throw a human being around like a bag of sardines is extremely disturbing. [Daily Mail]
