My friend/kung fu brother left his apartment a week ago going to work as usual. It was broad daylight when he was walking out to his car. Right when he opened his door to his car two men came up from behind him, pulled a gun on him, and stole his car. He didn't do anything but give up his car. I think he did the right thing?

What would you have done? Also, do you carry weapons on you to protect yourself when this happens? I believe he usually carries a knife on him, but didn't use it or even try to go for it.
