We don't know half the stuff that went on during the Iraqi invasion. Hard to tell who the bad guys are, I'm sure the US troops went tearing through houses looking for weapons stashes, and sometimes, they picked the wrong house. Also keep in mind, we carpet bombed these guys for days on end, collateral damage was done, I'm sure some of these people had their brothers and sisters killed. On top of all that, with Sadaam gone, life in Iraq isn't necesarily better than now than when he was actually in power. Unemployments out the window, these people want thier country back.
