The Geneva Convention does not apply to disguised (non-uniformed) combatants; they are to be treated as spies (or murderers — if engaged in combat when caught).
So you’re arguing that what took place at AG was okay?
There had to be laws or regulations that were violated or why else were careers destroyed over it.
I maintain the effect of My Lay and AG were the same in the eyes of the world in general and the American people in particular. That’s not because of journalism. It’s because collectively people make up their minds.
In neither case - ML or AG - did it have to happen.
