Certainly would help provide the Israeli's cover however, when the video footage starts to roll in of children lying dead in the streets...
There may not be live transmissions of events coming out of these 'military zones' but there is going to be taped video....lots of it!
If the Palis filmed any attrocities by Israeli troops, it's not going to look good for Israel. Remember Rodney King? The troops have a tough mission. I think these brave guys are going to look like monsters if there's video.
