Might be true.
Someone else pointed out the Bearded Ones were most likely Iraq / Afghan war vets/contractors who need the beard for masculinity cred among the Muzzholes.
Probably true. In which case they are BLM contractors now and I have no idea how they end up with U.S. LEO enforcement credentialing in that case. They aren't Park Police, Marshall's service, or anything usual. Maybe deputized BLM officers?
Undoubtedly they have some flimsy legal fig leaf.
