I saw the video and it also shows a motorcycle cop sitting up the road watching the whole thing. Most likely had orders to stand down. The mayor lets antifa do whatever they want including taking over a few city blocks and routing cars around it. Meanwhile, I would imagine there’s some sort of law on the books that says only police can direct traffic.
Slowly I turn, step by step...sooner or later it is going to happen when the righteous in this country say we have had enough.
Abbott and Costello sketch is a good example:

Nice of you to give the benefit of the doubt. I am inclined to think cops in that part of the country are just as liberal as the protesters.
