Bottom line, the 17 year old won’t be messing with the 15 year old again.
This kid's stitches will be out and his bruises healed before this even goes to trial. If Dad ends up in jail for assault, and kid ends up with a slap on the wrist....
Daughter will be at the age of consent soon, too, and will probably be pretty ticked off at Daddy.
It might send a message. But what's the message? Will daughter leave home, never to return, the minute she turns 18?
I'm not defending the boy. He needs to keep his penis in his pants. I have three sons myself. We teach them about respect and responsibility. All parents should.
A seventeen year old is not a child, but neither is a fifteen year old. They are both, however, minors. The boy committed statutory rape, and he should be subject to the full penalties under the law. But taking the law into his own hands wasn't the act of a rational man. It was an act out of rage and frustration, and although I sympathize with the emotions, actions provoked by them rarely benefit anyone.
