An interesting conversation with Goodlawgic and Robert Goveai regarding Presidental Pardons.
"Article II, Section 2, Clause 1:
The President shall be Commander in Chief of the Army and Navy of the United States, and of the Militia of the several States, when called into the actual Service of the United States; he may require the Opinion, in writing, of the principal Officer in each of the executive Departments, upon any Subject relating to the Duties of their respective Offices, and he shall have Power to grant Reprieves and Pardons for Offences against the United States, except in Cases of Impeachment."
He's arguing, essentially, that the pardon, as stated is for "Offences" against the United States, not the person. His argument, and not having any background in law thought this myself, is that this language suggests that those offences have to be known at the time of the pardon and I would argue must be stated. There is nothing to suggest a "blanket pardon" is Constitutional.
Fascinating ...
