America, where property matters more than people. You guys are aware that burglary isn't considered a violent crime, right?
Let's be real here, if the kids that got shot were white and the homeowner wasn't this wouldn't be a case of self defence. Additionally, how the hell is it possibly self defence when you shot three people? The other two teenage boys kept coming after seeing shots fired? Pretty doubtful. The kid probably waited for the burglars to get in so he could get the drop on them. I will not be surprised if it turns out that one of the kids was shot in the back.
It was a group of armed men with deadly weapons invading his home who he first tried to threaten. It was almost certainly intended to be a violent crime rather than a simple robbery, so your usual gutter-tier trolling is debunked.
You seem to think anything a person carries is a deadly weapon. We're talking about brass knuckles and a knife here. Seeing as these kids broke in at night I have a hard time believing any of the weapons were identified prior to firing. Additionally, they broke into his home to steal things, not to assault him. They likely had no intentions of violence.
You have no clue if anybody was threatened just like I have no clue if he waited to get the drop on them. The only person that claims words were exchanged shot and killed three people so one has to question the source.
For the record, this is only a debate because it is in America. In any other country you would get charged for shooting these kids. Bringing a gun to knife fight is actually upping the level of violence, not reducing it.
Feel free to risk your family's safety on a maybe. I'm sure as hell not going to. Maybe they had no intentions of violence, but I guarantee that would change the second someone woke up and saw them. They sure as hell didn't bring weapons along for fun.
