You must have pop-ups blocked. Their analysis includes the Founders commentary. It is contrary any your position.
From “Pardon Power”
“A reprieve is the commutation or lessening of a sentence already imposed; it does not affect the legal guilt of a person. A pardon, however, completely wipes out the legal effects of a conviction. A pardon can be issued from the time an offense is committed, and can even be issued after the full sentence has been served.”
It appears that, as of 1867, pardons could be performed for persons who committed crimes which were not yet known, but performed before the pardon occurred.
I stand corrected, unfortunately. This means the Clintons can be kept from all harms they've ever done, forever.
We will have to go after the Clinton Foundation and any new crimes they commit, going forward.
This is disgusting.
