Another sign the apocalypse is perched upon our doorstep: Wannabe cannibal cop

I imagine they will have to amend that slogan that the NYPD is New York’s Finest.
One New York City cop allegedly isn’t all that fine.
Gilberto Valle was charged today with plotting to kidnap, rape, torture and kill women he had identified and catalogued on his computer, and then cook and eat their body parts.
Valle sent numerous emails and other Internet communications about the ghoulish torture and cannibalism scheme, according to a criminal complaint. There was no information that any women were harmed.
How can a guy, let alone a cop, be wired with such a sick appetite?
