I don't have all the facts on this case and we'll know more later, but my impression after listening to the 911 call is that this was probably an improper use of deadly force. (So I'm posting in this section as a counter-example.) Maybe it was legal, as Texas law and jury culture appear more permissive re deadly force, but it appears at least morally improper to me. I bristled at Bush calling my fellow minutemen "vigilantes" a couple years ago, but there are indeed a few out there with that mindset and this case appears to be the real thing, based on my limited information. It just seems he went out intending to use deadly force and the shooting happened so quickly with no apparent counterfire or audible scuffle. I wish media would focus on the many other, more clearly legitimate DGU's out there. On the other hand, what do you do if the police aren't protecting your neighborhood? Just move?

Mr Horn saw Miguel Antontio DeJesus and Diego Ortiz getting into a neighbour’s house at around 2pm on November 14. According to his lawyer, he grabbed a 12-bore shotgun and called the police. He spoke to a police dispatcher for several minutes during which Mr Horn insisted he wouldn’t let the intruders get away. The dispatcher repeatedly told him to stay inside as officers were on their way. When the burglars crawled back out of the neighbour’s window carrying a bag, Mr Horn told the dispatcher: “Well, here it goes, buddy. You hear the shotgun clicking, and I’m going.” A few seconds later, he could be heard warning them not to move and then came the sound of three gunshots.
