If a parent could be confident that the pedophile would be punished immediately and removed permanently from society these type things wouldn't happen.
And if a frog had wings he wouldn't bump his ass from hopping.
An accused pedophile is entitled to a fair trial like anyone else. I know the parents go through hell, but that isn't an excuse to cut corners. Anyone can make an accusation -- I could accuse you now. Would that make it okay for your neighbor to stab you in your bed?
