You sir are an idiot. B17 pilots were lucky if their bombs came close to hitting their targets. They didnt have precision munitions like we do today. Of course there were civilian casulties. That is why they call it collateral damage. What is being discussed here on the other hand is purposely moving from house to house and systematically killing unarmed women and children. Accidental deaths are not being alleged. The Marines stated the dead died from the IED, not gunfire. Now they have backtracked and admit they were shot. Duh?
