"Yes Waco was a mass murder of civilians, but done due to poor leadership"
You are correct, it was poor leadership, but the footsoldiers happily followed the orders of their leadership didn't they?
We only understood after the fact that the ATF leadership was a bunch of idiots who ended up killing by their orders lots off innocent people. You can't blame the footsoldier in this situation just as you can't blame the footsoldier for following what he thought was a lawful order in any combat situation.
