Now that I'm on a computer, I'm genuinely shocked anyone feels it's ok for a grown man to attack a kid who is seemingly in a consensual, legal relationship with his daughter. Firstly, it's his daughters decision, not his. If she wants to act like an adult, then he should treat her like one. Christ, rebellious teenagers are more likely to do something if it actually feels rebellious. He's also no doubt created an issue in his own relationship with his daughter, regardless of the criminal side of it. It just reminds me of the way my own father reacted all too often.
Why should it be acceptable for him to act like a child and attack the kid? It simply isn't and it doesn't come off as something any good father would do. I reckon a good father would take the approach that the kids are acting like adults, so treat them like adults and trust them to be safe. Talk to your f**king kids. Forbidding and punishing does very little. Why should the kids respect him if he clearly doesn't respect them?
