Ha! Whatever dude.
There are rules to combat, and things that you just don't do.
If one of my soldiers had shot a captured enemy combatant, he would have earned a prison sentence. Now it happens, sure, but that doesn't mean its right or endorsed. And when it does happen its punished severely unless there are extreme extenuating circumstances.

Same thing then. It happened, but was not wide spread, and those that did it without a dang good reason were ostricised and punished. Galland himself said he regarded it as murder.
You implying that because it happened on extremely rare occasions that it should just be accepted and condoned, which is utter BS. It was bad conduct then, its bad conduct now.
But of course armchair warriors think that anything and everything goes.
