To use the fact you were only following orders to escape prosecution. Used by Nazi
Germany's military officers in Nuremberg
when they were on trial for their treatment of the Jews, when they claimed to have nothing to do with it, only doing what they were told to do.
It is seen elsewhere in history... one example would be Oliver North's trial after the Watergate
scandal, in which he claimed their illegal activity was just them following orders.
We're not ashamed of killing innocent civilians; we're just following orders.
