Sheriffs are increasingly refusing to enforce gun laws they have determined to be unconstitutional, reported News 21. Although the U.S. Constitution does not mention sheriffs, the position is listed in state constitutions – and most of the nation’s 3,080 sheriffs are elected, and not appointed like state and city police officials. The anti-government “Posse Comitatus” movement, which gave birth to sovereign citizens, believes government is illegitimate above the county, so county sheriffs are the highest legal authority in the U.S. Right-wing groups such as the Oath Keepers and the Constitutional Sheriffs and Peace Officers Association have repackaged some of these ideas, while downplaying the Posse Comitatus movement’s overtly racist and anti-Semitic elements. “I made a vow and a commitment that, as long as I’m the sheriff of this county, I will not allow the federal government to come in here and strip my law-abiding citizens of the right to bear arms,” said Sheriff Mike Lewis, of Wicomico County, Maryland.
