If you are talking about the riots, their purpose is the overthrow of the Constitution. It has been in process for a long time and is funded by people like George Soros. Officials have noticed patterns in the looting, where one group breaches the building, then another group moves in to do the looting, and a third may set fires.
Just look at what the Democrat party now stands for. They have revolutionaries in the House and possibly the Senate, but surely in the bureaucracies.
