Amazing, how some (Not all) men can even ask, how a man with power over teen-age girls taking advantage of them sexually can be illegal, and then we see cases like this.
Where a father, who wants to press charges for what that man did to his gets arrested.
Not the man that molested them.
The truth is, that the legality of the sex crimes is pretty irrelevant if the abusers aren't brought to justice, and the Father gets arrested for it. (When the father, and the abuser aren't one in the same.)
