Claims that the Marmara was fired on from Israeli ships or helicopters have been quietly forgotten.(It was paint, not blood Lox.)
The boarding was legitimate.
The boarders were met with "organised and violent resistance" according to the report.

That much is factual.
How the vastly outnumbered boarders should defend themselves from such an attack can only be a matter of opinion, and much easier to form such an opinion when your own life is not in danger.
