I get tired of the little jerks tearing boards off my fence so they can cut through.
But I haven't shot any of them yet.
The parents of the dead teen probably got a good laugh at this guy complaining about their son's violating this man's private property. You can't justify shooting a teenager over walking on grass. And you can't justify parents failing to discipline their children to stay off other people's grass.
The liberal solution will be to outlaw some more firearms.
The conservative solution will be to demand more accountability from parents for their children's behavior.
