When people circumvent these standard practices, then I have to assume their "Intent" is to attack me unaware, dispatch me with whatever means necessary (read kill me) and then take whatever they want.
The man said he had been robbed of his weapons, is it not logical to believe that these people were carrying them? So he was in danger, he was afraid for his life and had every right to shoot them.
How the hello can you defend punks who steal what you work so hard to buy? Their life is not worth more than mine, and if they break into a home and they get shot, too damn bad.
You live in a fantasy world if you think that the people who break into your home will leave you unmolested if you simply tell them to take whatever they want. That only empowers them to do more, because you are telling them they are safe from you trying to either stop them or trying to escape and call the cops. Hell, you may as well as just called them up and invited them over to rob you.
Really? How do you know what their "intent" is? How much do people hate to get to a place where they shoot them dead when you're in no danger? How paranoid do you have to be in order to be so afraid to lose a possession that it's worth more than a life? I'm not saying give your stuff out, but there's a lot of room in between those two extremes.
It's too bad common sense has been lost for some.
