What every pardon defender said will happen, did happen. Trump and the DoJ are going after everyone they can. If Biden hadn't pardoned Hunter, the J6 comitee and others, they would have been indicted too.
In retrospect, Biden did the correct thing.

You may well be correct. However, I do think there will be an appetite for justice after all this is over, and I don’t think it’s a foregone conclusion that a future administration would go back and look at people from the current administration.
It’ll all come down to who’s making the decisions at that time, and whether the political calculus works out one way or another. I think it’s too early to speculate as to what an administration that is 3+ years in the future would do.
