if he is old enough for sex he is old enough to move out and get a job
NO NO NO!!
Not this time Gerry! This was not a simple case of lust, rape is violence.This is not your typical 15 year old with active hormones this is using sex as a tool to do harm to another person/s. These kids have a sick and evil mind and it has to be stopped now. I can't say for sure that the porn did it but I can say that because they acted upon their feelings that makes them quite dangerous. They need to be locked up for a long time.

Since he is old enough to rape, he is old enough to go to prison.
