What I find most-interesting is that this is the leading Israeli daily newspaper that's publishing this, and that it doesn't pull back any punches. I'm actually comparing it to the AlJazeera article on the same (http://english.aljazeera.net/news/middleeast/2010/05/2010531...), and, honestly, the Haaretz article evokes more sympathy and more clearly states the plight of the activists on the flotilla.
Interesting tidbit: AlJazeera says "Israel 'attacks' Gaza aid..." with "attacks" between quotes while Haaretz says "At least 10 activists killed as Israel Navy opens fire on Gaza aid flotilla"
