There has been a lot of similar approaches to gaza strip by multi-national flotillas. They all have been secured and controlled and no harm were done to their passengers. This time it was different. I think Israel was also intimitated by the presence of islamist militants on the ship. I'm sure that they had the intelligence about passengers. For this reason they acted with rush and mavi marmara had more political support than other flotillas and was also supported by the Turkish and international media. They knew this and this maybe caused panic. I don't think that their initial intention was to kill people before they landed. It would be a greater mistake. But once they landed, they lost the control of the crowd. I think the commandos that were sent to mavi marmara were more specialized in combat training than riot control. I think it was a decisional mistake by the higher ranked officials to send such unit. It should have been done more effectively and without casualties.
