The reason there is no news reporting of numerous horrible atrocities committed by the US in Iraq or Afghanistan is that...there haven't been (m)any. There have been potentially needless but non-criminal incidents, and accidents, which are documented. There have not been many genuine crimes. (I believe there were more in Iraq than there have been in Afghanistan; in Iraq there was a military unit running a brothel, several cases of detainees potentially being abused, etc.)
The crime in Afghanistan and Iraq, if any, is that we're wasting huge amounts of "blood and treasure" for a mission which isn't in the US vital national interest. As far as how the actual war is being conducted, it's about as bloodless as an occupation can be. We're effectively trading combat effectiveness and huge amounts of money for casualties on both sides.
