BW said "(Although based on my standard a trial isn't necessary, just a summary court martial which identifies their position, the crimes perpetrated in the conduct of that position followed by a swift death penalty)"
That's pretty much the textbook definition of a kangaroo court.
Nuremburg was a BS court process anyway (Donitz and Ribbentrop's trials alone being more than enough to discredit it)
My system would regard any service in 1941-44 in, army command, army group command, high level OKH/OKW command and staff of those groups as prima facia evidence of support of the operations of the einsatzgruppen; a crime against humanity which would be punishable by death
The only appeal to offer is if the person is accused of having held that position and didn't actually do so; otherwise anything they have to say is completely irrelevent
So if one was trying Spediel for example... the charge is you where army group south chief of staff and as such where responsible for facilitating the activities of the einsatzgruppen; where you or where you not in this position? Answer is of course yes...The penalty for supporting the activities of the einsatzgruppen is death; the prisoner is hereby condemned to death by hanging; next...
