Your point seems to be that 1) the shopper was unjustified because he wasn’t threatened and 2) he wasn’t asked for help.
My point was that 1) he saw someone else being threatened. Isn’t that enough justification 2) If not, maybe he fellt personally threatened by the presence of the knife and the display of the willingness to use it violently 3) Who cares if he was asked for help
Just don’t threaten to use a knife on somebody to get money. If somebody, like this theif does, then that person is coercive. The self-defense exists for free-will. Thief threatened free-will. Obviously the shopper saw the event go down and he or she acted in self-defense against coercion. The coercion is present. Now self-defend.
For clarity. So that we understand what we are disagreeing over and where we agree so that we more rapidly hone in on the key issues.
What absolves this gentleman is that the robber or any of his agents can make a principled argument against him wielding deadly force, since the robber has already demonstrated that he thinks this is a perfectly acceptable norm. Any argument against the gentleman would involve a performative contradiction. And I would still say he’s a hero and the clerk is an ungrateful rass.
You didn’t answer the challenge. The point is that the shopper is justified whether or not the shop keeper asks for assistance. This was the point I was getting at that you ignored.
OK, maybe it is. But the moment the robber begins the assault, the shopper is justified in using as much force as he believes is necessary to end the assault while it is taking place.
So, threatening a person with a knife gets you death penalty on the spot ? Is there any further justification for that, or is it just self-evident ? I agree that armed robbery is a serious crime, but I’m not sure what libertarian legal system has determined that DIY death penalty is the proper response…
