To be an effective child molester one has to have a certain charm about them. When caught this charm along with their lie that, "It will never happen again," more often than not convinces others not to report their crimes.
However slight, if you suspect that someone has had sexual contact with your child you need to report it. Let the authorities sort out the facts. In our day and age it is very hard to have actual charges filled against you unless there is adequate evidence. We need to get the pedophiles on the radar screen.
