The purpose of the arrests are simple.
DO NOT RESIST OUR AUTHORITY.
What is or is not illegal is irrelevant to
those in power and their badgemonkey
thug muscle.
What matters is their authority is accepted
without question.
They were arrested for criminal trespass, not for illegal display of firearms. Go figure.
No kidding. Did you see the Brownshirt Badge Blimps in the video?
