I understand your position, I just disagree. We as a society, baby kids way too long. A 17 or 18 year old male is perfectly capable of acting like an adult, and not picking fights with people. Especially people bigger than him.
Your attitude is a less extreme version of the attitude of mothers crying to press after their criminal kids "didndunuffin" and get capped.
I just am out of outrage at feral kids that are old enough to know better starting violent encounters and then hiding behind their age when the "Find out" part gets there.
Not going to go to the Matt defending teach either, but if no one is seriously hurt, call it a learning experience and move on. We'll see what the DA's decide, I guess.
