"Moot", not "mute". Moot means (in this context) irrelevant or not admissible in court. Mute means unable to speak. So, the argument is still presented, so it's not mute, but it is moot, because it's not going to fly in court.

unless it is mute, as in "this argument makes no sound amongst all the other arguments. It has no voice of its own".

:D sorry, could not resist.

Thank you, that's what I meant.

Not mute, "moo". It's like a cow's opinion, you know, it just doesn't matter.

The Nürnberg trials went after a few high ranking Nazis and the "Entnazifizierung" (removal of nazis from official offices) only went after the very hard cases.

There were still thousands of nazis everywhere in government institutions like courts and police. The German term "Altnazi" (old nazi) describes nazis that were able to fly under the radar and still do their jobs until retirement.
