@Scustin Bieburr how would you rank the presidencies of Reagan, Bush Sr., Bush Jr., and Trump from most corrupt to least?
That doesn't really matter who is worse. They've all done things that are illegal and yet here we are. Guantanamo Bay was wildly unconstitutional. you're not supposed to be able to arrest someone purely on suspicion and put them in a prison without a fair trial and yet here we are.
Putting a president in prison would make america look like the countries in Latin America and Africa that american politicians love to look down on. To them, the political systems in those countries are jokes and people getting charged and locked up proves their world view. For the sake of american 'prestige' they'll never jail a sitting or former president.
