the SCOTUS expanded that immunity to other acts of a president not specifically in the constitution as his duties, giving what they call presumptive immunity, and then tied the hands of criminal prosecutors by saying the white house witnesses or accomplices even, can not be called or forced to be witnesses or admit testimony to the crime ...due to a sort of executive privilege for executive duties.... because the President was involved and his conversations with his admin were private or part of his presumptive duties...just utter bull crap! Even if admin and he were discussing a criminal private act and not an official act....you can't call the president's executives to the stand or subpoena them....
You tie the hands of the DOJ and law enforcement investigating crimes making it impossible to charge or try them, even after leaving office.
That is the part of their decision that is GOD Awful,
And makes any and all presidents immune for their crimes. (And possibly co-conspirators too)
Make the presidential position, ABOVE THE LAW.
so basically, he's above the law
