Pedophilia is not curable. Those who enter treatment with a desire to get better usually need lifelong therapy and medication. Usually they are given antidepressants to reduce the drive to molest, in addition to hormonal medication to reduce the sex drive. Our best defense for our children is to pay attention. Ask the school their policy on reporting possible offenses. Do they screen employees. How do they handle complaints? Teach your children about these people so that they know what to do when an adult asks something of them that feels creepy or weird. Encourage your children to speak up when something feels wrong to them. Blindly obedient children make easy victims. Finally, try to stay involved in your child's school, and get to know the teacher. Your visibility and observing eyes can act as an inhibiting factor for a molester.
