Israelis on trial in Turkey over Gaza ship deaths

Surely all Israel had to do is to hand over the hours and hours of video footage that its forces confiscated from the passengers. Surely this will not only back up their claims as to “who fired first” but will also help to refute allegations that passengers were shot in cold blood. It is hard to imagine why Israel is so reticent to do so…..Unless of course the footage corroborates the testimony of eye witnesses. Then I could understand the importance of keeping it all under wraps.
