If the civilians become willing part of the cover and concealment of the enemy, they thereby become active combatants. In Viet Nam we had children ride bicycles with backpacks full of explosives (satchel bombs) so the could get close enough to the GI's to throw in a tent or something like that. What the left dosen't understand is that you can't fight a gorilla force with conventional methods and rules of engagement.
I was there and can verify your statement. We never knew, until after the facts, who was who, and who wasn't. Always on guard and always watching was our motto, and I'm sure the Marines involved in this operation felt the same way. I cannot believe the Marine Corps General out in San Diego relieving his officers two months after the fact with his B.S. findings. Is it no wonder we are still tying our military's hands behind their backs with a$$kissers like that General? In my book, he should be relieved, not the Captains.
