You didn’t REALLY need to ask that question, did you?
Of COURSE they are unionized.
These are DC Police? I have been to a bunch of events down in Washington, and the police we encountered in various demonstrations and counter-demonstrations seemed largely sympathetic to the conservatives and their causes, not the moonbats. We spoke to a group at Arlington Circle (outside the Cemetery) and they were ALL very conservative, didn’t like the moonbats and anarchists at all, saying so (off the record, of course!)
Now that I think of it, they might have been State Police, not DC. But DC Police have generally been pretty good to our side.
