Perhaps, but I'm of the opinion that if a sentence is unjust, or if the means to convict violated the defendant's rights, then the defendant should walk. While this may seem unreasonable, it's the only way to check the state which has unlimited resources when it decides to go after somebody.
I don't really have an opinion on this case because I'm not completely familiar with all the details. It's certainly going to be contentious.
The idea of a pardon is exactly that: it erases the record of the crime/conviction.
I think you are thinking of a commutation. That ends the punishment while not absolving the person of the crime.
So the January 6th criminals who got pardons no longer have a criminal record (on this count at least). The 14 people who were only granted commutations are still counted as felons.
> As these opinions confirm, a presidential pardon removes, either conditionally or unconditionally, the punitive legal consequences that would otherwise flow from conviction for the pardoned offense.
A pardon, however, does not erase the conviction as a historical fact or justify the fiction that the pardoned individual did not engage in criminal conduct. A pardon, therefore, does not by its own force expunge judicial or administrative records of the conviction or underlying offense.
