A show trial is designed to deflect the blame for those failures to someone else
In this case Donald Trump & MAGA Republicans
A show trial is designed to influence the general populace to dislike and condemn the designated subject(s)
Justifying their destruction
Except that no one is stopping Trump from presenting any evidence he has that the election was stolen, or that the people there were mostly peaceful and setup by the FBI, etc.
He’s not really even lifted a finger to combat any of this, including leaving now-broke Giulliani to defend himself in his disbarment trials. Trump is a shadow of his former self, and should be doing more than a few tweets while our whole movement is being labeled traitors.
