Whether the flotilla was justified is debatable (I personally think it was, due to the fact that it's purpose was an attempt to break the blockade, rather than just deliver stuff), but Israel's actions are certainly not. Was it impossible for the Israelis to snare the propellers of the ships, and then tow them to shore once the protesters had surrendered? Or was it really necessary to for the helpless, vulnerable commandos to blow away anything that moved, as a few sticks and knives were used by the fearsome civilians?
