Many, if not all, police in Portland, and possibly other cities, are antifa. Remember the cities reduced their force strength several years ago only to increase the force with higher pay the following year or two. This was done to insert antifa/deep state in the force.

If they bust people, the arrestees just get set free with a slap on the [officer's] wrist and/or the officer gets fired
If they don't bust people, they get ragged on
