His house had been broken into, I think, eight times. The recent burglary netted the thieves two firearms and about $10K worth of stuff. The girl was a drug addict, and they are suspected to have been involved in prior robberies.
Friends and family all admit this, but say the usual thing: "He should have just wounded them, not killed them."
How about this: Don't break into people's homes. When you break into a house, there may be someone on the other side who makes sure you don't leave alive.
Not saying his final execution-style shots were right, but that doesn't change anything. They're still dead. "But he can't do that! That's wrong! That's against the law!" Yeah, but he did, and they're dead. Why do some people (parents, friends) expect the victims to obey the law while making excuses for the original felons?
Actions have consequences. I hope those two learned that.
