I'm not saying the protestor can't control himself. I'm saying the organisers of the protest has less control over that individuals actions so has less culpability.

Whereas the police should have a culture of not throwing rocks, so serious questions should be asked of the leadership.

If you have a failed state such that large areas aren't under government control. And some warlord attacked your country, would you say that was a declaration of war from that entire country? Or would you accept the government didn't have control?

Gaza is a messed up place. You wouldn't necessarily expect all the groups to hold to a cease fire, like you would a nation with a single unified command structure.

A breach of a cease fire by Gaza says something different than a breach of a cease fire by Israel.

I'm not saying anything about individuals, I'm saying different group structures have different amounts of control over individuals in that group, so it isn't reasonable to hold them to the same standard.

To go back to your last example. Should you be held responsible for your son throwing rocks? Should that not depend upon the level of control? Or should we treat a dad handing his 5 year old a rock and instructing him to throw the rock at the police, differently to the 25 year old son that went there by him self?
