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.
There will be videos of lots of corpses though, and people like you will say, "Gee, I hate to believe it - but obviously the IDF went on a rampage and killed unarmed civilians," etc.
