Are you saying he shouldn't have been prosecuted for that?Fine to quibble about process timing and litigants' motivations, but the fact remains that the case was actually processed quickly as merits cases go.
2 centuries of precedent? If I recall correctly, the court's analysis began with something along the lines of 'this is the first time in the history of the country that a for president has been prosecuted criminally for prior term conduct.'
The over 2 centuries of precedent was the peaceful transfer of power in case there is any doubt, in case you may have forgotten.
