From what I can ascertain, the Israelis launched a "surprise inspection" raid at two in the morning and a riot ensued. One person was killed. I saw several people in that video (no sound here, either) with gunshot wounds to the extremities, so I'd have to say that the Israelis seemed to have exercised some actual restraint. You don't shoot somebody in the calf if you're actually trying to kill him.
I'd be willing to bet that there are a ton of more egregious issues with Israel's detention of political prisoners that merit some outcry. It would seem that a disproportional number of Palestinian prisoners wind up dead in Israel's custody. Certainly a bigger reason for concern than 1 dead from the suppression of a prison riot.
Something that's annoying as all fuck is the difficulty in finding legitimate info about the goings on over there.
