A couple of kids jump a fence into an old guys backyard. The old man assumes the kids are criminals and shoots at them, hitting one. He is well within his rights, according to the Castle Doctrine. The kids run home and mom takes them to the hospital. On the way, her car gets hit by a drunk driver and mom dies.
I am sure a lot of people will blame the old man for pulling the trigger, but I do not think he's at any fault. The primary fault belongs to the kids trespassing/breaking and entering/jumping the fence or whatever you want to call it. Blame the kids. Yes.. blame the stupid kids for being lazy on their way to the party.
Next blame.. the drunk driver. Ultimately, the tragedy is due to this asshole.
