Police departments that condone these leftist friendly riots are just as evil as the rioters. Any chief of police who allows this deserves contempt as does their department. They have forsaken their oath for political benefit. They are partisans not police at that point.
Which makes them extremely dangerous.
I notice that many if not most of the Antifa shows up in college towns. Having a university or two nearby used to be a draw. But that is also fertile ground for Far Leftists..
Police should be made aware that Antifa considers them fascist.
Police should be made aware that BLM terrorists have repeatedly assassinated police officers.
Police in Charlottesville sided with their enemy because their crooked Democrat governor wanted them to.
