What the hell are you guys doing where you're shot at and/or sustaining "moderately serious injury'? I fought a guy once in 6th grade, bigger than me but kicked his ass when I went loco on him. Nothing since, though. You guys living in some big crime area?
Would I fight a hijacker? Sorry to be politically incorrect, but an Islamic one, sure. Wouldn't expect to live otherwise. Would look for the best opportunity, try to get others to join. If the knife's at my throat? Well, do I think it's a warning or am I the example? Judgement call I guess.
