If you don’t know about chatroulette, then you don’t know about the latest in “To Catch a Predator” technology.  Here’s what happens:  You have a video chat with someone TOTALLY RANDOM.  10 seconds until someone’s bought the movie rights for the best stalker/chatroulette serial killer movie.  My guess is it’ll be called “Put it all on MURDER.”  Get it?  Because it’s got roulette in its name.  Clever, right?
