The troops didn't STORM the ship but hailed for it to stop (all the other ships did), and when it failed to do so, the troops boarded the ship with PAINT GUNS. The soldiers did not expect to be attacked with heavy chains and knives and after several injuries some backup armed troops had to open fire in order to protect their lives from those so called 'peace activists' . Later on it was proved that the men on that ship were sent from a Turkish group linked to El Keida. Please look it up. The only thing Israel did wrong is have those two clowns Bibi and Barak in charge and step into that clear PR trap !
