So while we're in agreement that Nixon was a criminal, you're saying he should not have been prosecuted...because people had other reasons to dislike him beyond his criminal acts? I fail to see how allowing Nixon to escape justice allowed the country to Move On. It demonstrated to the public that in fact, there are different classes of people in this country, and the powerful simply aren't subject to the same laws as the commoners.
Therefore prosecuting him because he was an anti-Communist Republican would not have been good. While this doesn't address my greater point, look at all the bogus prosecutions of Reagan Administration officials.
My greater point is about the arena that Ford decisively closed off with his pardon. Historically, when a Republic degrades to the point where leaders don't dare lose power, because they'll lose their freedom and frequently in time past their lives, that Republic dies an ugly death.
Perhaps you weren't alive/politically aware back then, but the country did Move On, Nixon and Watergate, which had consumed it, often to the exclusion of very important external issues, just stopped being a, let alone the top issue of the day. We Moved On to the supposedly clumsy Gerald Ford (he did have a bad knee from college football, but this was greatly exaggerated), Whip Inflation Now, Swine Flu, but seriously, the general business of the nation.
The other point in time where Republics die an ugly death is the point at which the leaders no longer feel constrained by the threat of being held accountable for actions while in office. Ford's preemptive pardon of Nixon -- which forestalled a thorough questioning of Nixon's actions and a determination of whether he ought to be held accountable for them -- moved the Republic closer to that point, even if it also moved it farther from the point you are concerned about (which, of course, is always the one those in power want to avoid, and not out of any concern for "the Republic".)
> Perhaps you weren't alive/politically aware back then, but the country did Move On
It did, indeed, move on to the abuses of national security apparatus by later administrations (most notably under Reagan, Bush II, and Obama, though the Ford, Carter, Bush I, and Clinton administrations aren't without issues, as well) with a similar lack of accountability, and indeed an increasing acceptance that, while we didn't like it when it was the other side doing it, such abuses were just part of what happened, and even in the most egregious cases with the clearest involvement from the top, there was no serious consideration of accountability.
The Ford pardon secured and further institutionalized the Imperial Presidency.
I'm sorry, I had no idea that you were this far out there. There's not much point in debating you if we're not on the same page about the realities of his actions.
If you can't see the danger of changing the rules of the game and throwing people into jail based on that....
