When I was in Navy OCS the question of illegal orders came up. The JAG instructor said that the determination if an order was legal or illegal would be made at your General Court Martial.
My understanding, as well.
One lasting effect of this is all civilian deaths in a war zone are now viewed in this light by the media.
LOL
That is a very good line summarizing what can be a very big problem in many institutions. On the other hand, casual questioning of orders can quickly bring an institution to a standstill.
The Japanese have a proverb which captures the flip side of “The squeaky wheel gets the grease”: The nail that sticks up gets hammered down.
