HRW did an interesting report following up on the initial phase of Iraq a few years back, focusing on civilian casualties in air-to-ground bombing.

Their conclusion was interesting. They could not find a single case where a pre-planned target caused any civilian casualties, and were very complimentary of both the restraint shown by US forces and the ability to very carefully target leadership targets, building, etc., without causing civlian casualties.

At the same time, they strongly condemned many of the last minute incidents, most of which were targeted at the "55 most wanted", most of which were based on last-minute intelligence, and virtually none of which reached the intended targets, but did cause significant numbers of civilian deaths. On the whole, they are pretty fair -- which means they are going to be critical all around, both of the US and other countries.
