Steven Prowler, who taught English in Bangkok until he was caught having sex with underage boys was just sentenced to 10 years in a US federal penitentiary under the PROTECT act, which makes it illegal to travel overseas to have sex with children. He was a strange little guy whom I met during my short-lived teaching career. He apparently took lots of pictures of his little Thai friends, to whom he paid around 200 baht a gobble. I doubt if he'll survive in the general prison population, even those guys treat child molesters as the lowest of scum:
