Here’s an ABC News article on the story.
About a year ago Joe Horn saw a couple folks exiting his neighbors house, presumed they were robbing the place, called 911, and confronted them as they entered his yard. He the shot and killed both of them with a shotgun.
This was in Texas, and all homicides there go in front of a grand jury. They let him go.
Unless you live in Texas, don’t try that at home. Heck, even if you live in Texas it’s still not a good idea.
