Gimme a break already. The very nature of insurgency and guerilla warfare is that telling who is a bad guy and who is a good guy is extremely complicated. Old guys can shoot (as a lot of us well know), kids can carry grenades, and women can be strapped with an IED...and any variation on those things, as well. I'm sorry, call me names if you must, but I would ALWAYS give the benefit of the doubt to any US service member in a combat situation.
