Israel’s chief of staff, Gen. Herzi Halevy confirmed that the three were waving a white flag. He said the soldiers’ actions were contrary to the military’s rules of engagement. “It is forbidden to shoot at those who raise a white flag and seek to surrender,” he said.
What he really needs to acknowledge, is that the IDF is loaded up with extremists, who are hell bent on killing as many Palestinians as they can. They used to ply their trade in the West Bank, but they now have a larger theater of operations, and an excuse.
They have never been disciplined, and they never will be.
Hamas is not the only party that's hell bent on indiscriminate killing.
