Local police (depending on region) are corrupt as hell - this was the federal forces.

FYI about the same thing would have happened Jan 6 if Biden was already sworn in - remember that Trump & his cronies hadn't deliberately stalled federal forces from acting.

Because Lula was in charge, they were able to sign an order for federal forces *while the insurrection was still ongoing* meaning the feds could round up 1200+ of the insurrectionist bozos to process and charge them all on the spot.
