Andrei Vyshinsky rose to fame as the chief prosecutor during many of the infamous show trials of the late 1930’s in the Soviet Union.  A brilliant student, lawyer and lover of academia, he was a second level (never entering Stalin’s inner circle) bureaucrat who managed to use the deaths of those he prosecuted to advance his career.  Although the U.S. ambassador to the Soviet Union at the time, Joseph E. Davies felt that the trials were conducted to the highest legal standards (his book, Mission to Moscow was made into a terrible propaganda movie in 1943) they could only be viewed in that manner if you wondered why defendants who recanted were taken from the court room and then their written statements reversing their recanted statements were admitted and they were convicted (many who recanted were so badly beaten that they could not be taken into the public eye and were quickly executed).  As a side note, Ambassador Davies spent most his time antique hunting and sent hundreds of “finds” back to his home in the U.S.
