One of the most important things I learned while being a zookeeper for the state of Texas for several years is that 90% of white guys who are locked up for sex offenses against children didn't actually commit any crime other than pissing off a whore. It takes nothing more than a woman's word and a coached statement from a kid and a guy is facing life in prison, so naturally they'll take the plea deal despite being innocent.
The Feds like to pull the same stunt on white men who rock the boat too much, such as David Koresh, Kevin Strom, and quite a few others.
