killing someone who is trying to rob you

[Sponger.]

some background on the question...

i am at a bar last night in nicaragua with some people from my hostel having a good time, and this brittish girl decides to kill the mood by getting political and bringing up this incident and trying to critize people from the US for our violent culture or whatever.

she said that the guy shouldnt have acted in self defense, and that everyone should have just handed over their money. she also said there was no excuse for killing the mugger, everyone disaggreed, but it got me thinking maybe there are more people out there who think this way.



so, if you were approached by an armed gunman who demanded money, and you could kill him in self defense and escape unharmed, would you?
