The latest national child pornography bust took 27 possible offenders off the streets but not for good. After sexual offenders serve their time often they go back into society.
Doctor Rick Grieve at Western Kentucky University says for every offender caught and arrested that person on average had committed sexual crimes 8 to 12 previous times.
"We don't need to fear every sex offender because there are those who do recover... Problem is you don't know which ones have recovered," said Grieve.
Grieve says he believes behavioral modification works best which re-associates adults with pleasure and children with pain to the offender.
Although change is never guaranteed. In fact, Grieve says the success rate is low. He also says many of those seeking treatment are there because they have to be because of the court system, and not because they want to be.
