The official backgrounder says:
"The events leading up to and throughout the flotilla incident are recounted in the video, as presented by the team of experts led by Maj. Gen. (res.) Giora Eiland in the IDF's internal inquiry... The video [describes] the various ships in the flotilla and the courses of their attempted journey to the Gaza Strip, as well as the number and extent of Israeli response ships, aircraft, and absorption center for the ships' passengers. The video also outlines the orders given to the IDF soldiers boarding the flotilla ships, including the policy of using gradual force, and using live weapons only in life threatening scenarios."
There are plenty of people out there who will cling tight to their claims of an Israeli bloodbath and to the fantasy of the Turkish fleet being populated by peaceful idealists. This will not persuade them to think differently. But for the rest of us, it's a valuable and authentic look at the facts behind the claims.
