We Americans LOVE to approach life as if every accident is avoidable, every mishap is preventable, and every evil is stoppable. Sadly, they're not. A certain percentage of people don't see other people as human beings. Tough luck. The best thing to do is give the rest of us the ability to defend ourselves. Or we could attack the root of the problem and start building up the nuclear family again. There's nothing like a stable, two-parent traditional family to assure that the kids grow up into stable people.
