Usually, an incoming administration will drop any investigations of the outgoing administration -- out of some noblesse oblige.
However, in the case of the Obama administration, the next administration must continue and intensify investigations. We're not dealing with routine political corruption. In many cases, we're dealing with subversion -- if not treason.
Whether these people are pardoned by an outgoing President Obama or not, the width and depth of their subversion must be revealed. The next President must be a man of strong will...and he must appoint a committed and effective muckraker as Attorney General.
Sometimes they even become sons and brothers ala GHWB unofficially adopted Bill Clinton to be a son, and GW claims him as a brother.
I also remember how stoked freepers were at the prospect of GW cleaning the peoples house and reversing all those evil EOs.
Did GW do that?
Nope, sure didn't.
