Not only will they destroy people who cross the goals of the left, but anyone who dares defend them from the mob will be destroyed as well. They are making lists, and will destroy anyone who they deem worthy of destruction.
So now they are going to destroy the reputation of the defense expert witness from the Chauvin trial. Once they are done with him, any cop accused by the left will have no chance of being able to defend themselves, because no lawyer or witness will dare come forward.
This sets the stage for what communists always do. They engage in show trials before shipping people off to the gulag.
