Your quote of the story shoes that the home owner did jump directly to lethal force. If you disagree, then please tell me what non-lethal force the home owner used. Open hand soft? Closed hand soft? Open hand hard? Closed hand hard? Electrical device? Chemical deterrent? How did the home owner attempt to subdue and detain the teen?
I'm not contesting the homeowner's right to use lethal force, I'm disagreeing with his decision in this case.
