The possibility isn't 0% imo...but even putting aside precedent like the Obama administration I honestly think the Trump administration precedent is more telling on this.

Trump has violated so many norms and done so many things that used to be inconceivable...and yet I don't recall him ever making a serious hardcore attempt to "lock her up." Even someone like Roger stone was essentially given as red meat is walking free now.

Once you reach a certain level of power you become immune from consequence because nobody in that in group wants to set the precedent that they may be criminally accountable.

In the end I think the most likely change or new result of this all is it may no longer be gauche to speak Ill of your predecessor.
