This: "Since when do police protect anyone or anything from Trumpers?"
Here in Portland, the Proud Boys get special passes from the PPB. Last year during a demo/riot they had set up a sniper post in a multi level parking structure. Were they arrested? The PPB basically said. "Now boys, put away your guns you are free to go." Imagine if it had been anyone else, they would of been killed by the PoPo. Yep, it is a special relationship.
