The Israeli authorities thought the passengers were going to play by the usual 'rules' and passive resistance methods which have developed following the first world bank demonstrations, and the decided that they were going to surprise them and end it before the protesters could get their standoff and be dragged off in handcuffs in front of the cameras.
When the Israeli spokesman says that the protesters solely are responsible for the deaths that is simply a logical failure. Israel instigated this. Cause and effect - Israel is responsible regardless of how little they wished or planned for this outcome. They could and should have handled this differently.
The media reaction is not surprising, what was known was that possibly up to 16 civilians had been killed following a midnight commando raid. The rumor mill going wild, this person shot, this person wounded. The passengers included some very respectable names, EU parliamentarians and former middle east envoys, and journalist across the board have learned to be wary of any official Israeli -and while were at it also Palestinian- version. There are no official sources not concerned with covering their asses and serving their agenda, none the least bit interested in self scrutiny or getting to the truth.
Yes, we have seen passengers attacking the boarders, shooting in self defense is a plausible scenario, but what else is on those video files. If it's anything detrimental to Israel surely we are never going to see it.
