Well, I'm no Rambo but I'm pretty capable of taking care of myself HOWEVER as soon as I notice people getting killed I would make sure that I NEVER seperate from the others, and I would seek out the most well known popular person (the star is never killed right?) and lastly IF I actually found myself in a position where I knocked down or shot the killer I would not just walk away assuming he is dead, I would keep going at him until there was nothing left to come back after me!!!!!
