Before the boats left they knew they would not be allowed to cross the blockade. In fact that's why 5 out of 6 of the boats were stopped without incident. The last ship was a ringer, their job was to intentionally provoke Israel into a confrontation to create this staged international incident. Any neutral look at the available video's reveals the last ship was clearly at fault and started the conflict with the hope of people being killed, just for PR purposes. The "peace" activists are guilty of murder, if the case was tried in any U.S. court the clear premeditation of the activist to provoke the fight would be enough to find them guilty.
