I have to agree with you, I'm sure when you see somebody that is carrying what looks like a rocket launcher, which could kill one of your buddies, you probably tend to act quickly. And it sure as hell looked to me like weapons in their hands, why else would the "rpg" guy be peeking around a corner suspiciously? As for the the innocent people, if you see people walking around with weapons in a war zone, you might want to gtfo of there before shit hits the fan. This is war, it's never going to change folks, might as well accept it.
