A part of me, at the risk of sounding like one of the CSTDT whackjobs we quote so much, wonders if this is Munchausen by proxy. Say, for instance, that you suspect that werewolves exist, and you want the world to know. If you're going through Munchausen by proxy, you won't just make like a Bigfoot hunter. You'll dress up like a werewolf, attack victims like one, and shy away from potential weaknesses of the werewolf, all in the hopes of waking the public at large up.
Then again, I might have played too much Hunter: the Reckoning (fuck New WOD), and his faith is what he says it to be.
My condolences to his family, and I hope those responsible are caught and brought to justice, whatever the case may be. And a big salute to the woman who tried to fend him off while the cops closed in.
