As I recall there were Sovereign Citizens of the Moorish persuasion occupying upscale homes in the Seattle area and claiming “ownership”.
Parasites.
I’d expect not to agree much with a group called Rise of the Moors, however, what have been shown is just some second amendment/open carry activity. Nothing illegal (well, maybe in MASS, i dunno the laws there) or alarming. Second amendment applies to all citizens.
