Unfortunately, our parenting skills only go so far... when they hit legal age they can do what they want. Trust me, I'm living it. My kid was down there, could have got involved but realized once bottles were flying around his head and the fires began, that being there wasn't the place to be! I told him I was proud of his actions... as I know the "grunt" mentality can easily take over when a bunch of cavemen fight over a shiny rock... and beat each other up over it. At some point you hope their conscience kicks in from those influences from your parenting. They should all be sorry for their actions, serve the penalty and hopefully learn from it. I expect there'll be some examples made of some people.... which is what it looks like the public wants.
