Could the man have requested another assignment for conscience sake? Unless he can prove that he was forced into his role, he shares culpability (like the driver in a robbery.)
According to reports he was an accountant at the camp and he requested transfer from the camp multiple times and was denied.... Don’t know if his claims are true, but if they are, this prosecution is nonsense.
Unless the prosecution can some how put him in a position of authority and power that could have prevented these deaths, this trial is a farce.
He did. He requested to go to a front-line unit and was sent to the Ardennes in 1944.
