What else would you call it? The Israeli commandos that boarded the Free Gaza Flotilla shot Furkan Dogan once in the chest and four times in the head at close range. Was he still resisting after the third head shot? Did five different commandos happen to shoot him all at the same time in the middle of the night with stunning accuracy? No, someone shot Dogan at close range and did so enough times to make sure he was dead well after there might have been any resistance. That's generally known as an execution.
Dogan is an American citizen. That's an uncomfortable fact for a lot of people, especially for our politicians who will do anything possible to cover for what Israel has done here. It's hard to cover for the summary execution of an American citizen. But they've managed pretty well so far. Do you hear any cries of outrage coming from America? No, didn't think so.
