Moot points really. Because of the political nature of their crimes they were rightly not prosecuted to the full extent of the law. It's 3rd world banana republics that use law enforcement to go after political rivals.
Every prosecutor wants to put away a dirty mayor/governor/president. That would be a huge feather in their cap. But it just isn't done that often in the US.
Think Scooter Libbey. They got him on the weakest of technicalities.
The burden of proof to put away politicians in the US is super high. They had to find $90,000 cash in William Jefferson's freezer before they would look into bribery allegations.
You often complain about Nazis. Well they were really good at imprisoning their political rivals. Look how that turned out. You need the burden of proof to be super high to prevent political witch hunts on either side.
