Dave, watch the video again. One of the insurgents around the camera crew had an RPG. It is very clear that it is an RPG and not the cameraman. RPGs are not legitimate self defense weapons in Iraq. If you would like I can find you some still frames with the RPG highlighted to help you. Also, you can find the official report which has the developed last pictures from the cameraman, these pictures are of American troops, so I am guessing there were some nearby if he was able to photograph them.

Read up more on the audio recording. It wasn't faked, it was edited to remove silences and to remove background noises. Now you can site that the audio recording can not be conclusively attributed to anyone and that would be correct as it was an open radio channel.

The carpet bombing and artillery shelling of WWII had two effects. First it did reduce the ability to wage war through the destruction of industrial facilities. Also, since we were bombing the living crap (killing) civilians in their homes, it broke the will to fight of the civilian population. We tend not to do that anymore, so we are ignoring a major component of how wars are won due to us wishing it wasn't true.
