I fully believe that the DOJ and the courts surrendered to the BLM/Antifa/DNC terrorists that would have torn this country apart if President Trump was allowed to win a fair election.
I'd suggest that the DOJ, the courts, and the rest of the D.C. bureaucracy have become its own fiefdom, accountable to no one, answerable to no one, and in place to keep and preserve the power they have. The term "Deep State" is relatively new, but I think the D.C. bureaucracy has been taking care of Numero Uno (itself) for decades.
BLM/Antifa have had little to do with it, IMHO.
