Usually you have to be convicted before receiving a pardon but I think Clinton changed the rules with his pardon of Marc Rich. Why not use it then - If it's needed.
Not how I read it.. source. I questioned that as well before I put fingers to keypad.
Can't use it if it might harm the Bush dynasty.
You don't have to be convicted before receiving a pardon. In 1974, President Ford pardoned Richard Nixon for any and all crimes and Nixon never stood trial for any. He was listed as an unindicted co-conspirator but he was never indicted.
Um, Ford/Nixon, anyone?
