I remember there was this one dude got caught, they found Duct tape, Rope, "lubricant", a camera, and a few other things in the back of his car..when asked what they were for, he simply said "Oh, I always have that with me"...
So at least one potential kidnapper/rapist is off the streets!
There was a website that was about a group of people that have devoted their lives to nabbing these freaks off of chat rooms and IM's. I would link to it, but the stuff is so disturbing, no one should read it, its just not right. I regret reading it, its scary that these people actually exist, and walk among us.
