Gideon, the palestinian throwing rocks was not naive, he knew the rules of engagement and exactly what the IDF are or are not permitted to do. He wasn't out protesting with a banner or in some other peaceful matter, by your own admission he was being violent. The IDF also retaliated with non lethal force in the terms of gas, the fact the grenade hit him was unfortunate but he wasn't targeted. Have you never heard of the saying TAKE RESPONSIBILITY FOR YOUR OWN ACTIONS. He chose to go out to protest and he chose to throw stones nobody forced him. As for the skunk whats your objection to that one? Is it wrong to use bad smells to break up violent protests now?
