Tiger Attack Jackassery
Suggestion for the San Francisco cops, in case they haven't already thought of it: Check the tiger-attack victims' cell phones.
If the current speculation proves true, and Tatiana was egged on and enabled by the teens she would ultimately maul, I'm guessing that at least one of them has video. This sort of stupid stunt -- dangling one's body parts before a fierce, carnivorous beast -- is exactly the sort of behavior increasingly demonstrated among teenage boys eager to make it on "Jackass," or at least YouTube. Kids these days tend not to do anything this recklessly dangerous without documenting it -- after all, extreme stupidity is a one-way ticket to Internet fame.
Time could prove me wrong, of course, but my gut tells me this stunt was made for the small screen. And if so, that raises a key question: Does anyone doubt that the video will somehow end up on the Net eventually?
