I had a friend that would be punished or grounded and it made no difference, he sneaked out the window and disappeared anyway. Aside from bars on the window(s) and the doors, he had it in his mind to got out and f*ck off. The moral of the story is nothing would make a difference, not even the Navy for this guy, he had to learn it the hard way, his way because of his screwed up personality traits.
I do see your points about the parent shipping him off to the other parent when in fact he was suspended. Either way, the parent(s) lost their perceived child (17 Y.O.) but it was never up to them, it was his choice to get into an altercation physically with an armed person.
Hopefully, the lesson learned form all this is be weary of that person you're about to attack as he(she) might be packing. The liberal left would like all to be at the mercy of the attacker while we on the right and free demand the option to look out for our own defense.
Speaking of conceal carry, I spoke to a clerk at a phone store about my employee getting mugged and she said "I feel for you, sir. I don't know what I would have done". I told her to buy a firearm and carry it to which she said "I can't carry because ^%$%& or bogus reason"
I explained to her that it was her constitutional right to protect and defend herself. Oh yeah, she is black so I'm going to assume she's been conditioned to believe that guns in defense is a bad thing. There's no reasoning with these idiots, they've been programmed.
