HRW: and their "pro-Israel" donors

""These casualties comprise a small fraction of the Palestinian civilians wounded and killed," it said.
"But they stand out because, in each case, the victims were standing, walking or in slowly-moving vehicles with other unarmed civilians, and were trying to convey their non-combatant status by waving a white flag." What is Human Rights Watch implying here? That other cases don't warrant an investigation? (thanks Olivia)
