Will I feel vindicated? No. Will I lose sleep over it? No.
I spend a lot of time in my life doing two activities that are very dangerous. Rock climbing and out-of-bounds skiing. On more than one occasion, in each activity I was in a situation where I thought "OK, this is it, I'm going to die." And the second thought I had in each one of those moments was "Well, it was my choice." So no whining, no crying, no feeling sorry for myself. I chose to ski off the backside of that mountain and out into the wilderness of the high Sierra. You figure that I was smart enough to read the map that called that section of the planet "Desolation Wilderness" and that I had some idea of what that meant. At least the 'wilderness' part - I was experiencing the 'desolation' part of it as I went.
My choice. Had I not made it out by nightfall, I would have froze to death most likely and whose to say that I didn't deserve it?
When that sling broke on me down in Pinnacles, well I chose not to check the equipment - a mistake I would never repeat. But, my bad, and I almost paid for it with my life, had my friend not been in the one exact spot that could save me I would have been some gooey mush at the bottom of the hill. Like I said, my bad.
So, at the moment he picked up that gun, (not even the moment he pulled the trigger) he was making a choice. He is old enough to know that shooting people will get you tossed in jail. Doing it in front of witnesses, well that's real dumb, but ....
And, everyone knows that jail is bad, and prison is worse, and prison in California is very, very bad. What between the Aryans, MS-13, the Crips and the Bloods its not a good place to be. And even though he will go to the CYA for a few years before the big time - Soladad, Folsom, San Quentin, those CYA maximum security places are not filled with kids who stole a bike.
So, he made that choice when he made his choice. Its tough, its rough justice. But its his choice.
That kid destroyed those families. Not the court system. Not me. Not society. He did the moment he picked up that gun and said "I'm going to shot him."
