The CSPOA unsurprisingly has its roots in white supremacy. The idea started through the writings of Christian Identity (white supremacist) minister William Potter Gale about Posse Comitatus which considered the country sherif as the highest government law official. White supremacist groups continued the idea throughout the 80s and 90s. When I grew up, I had always heard of talk of “constitutionalists” up in the mountains that were fine dealing with the sheriff’s departments but claimed they would shoot federal officers on site. The reality is that they were not constitutionalists at all but anti-government racists who tried to hide their racism under a very thin veneer of faux constitutionalism.
