The spread of the “constitutional sheriffs” movement—which claims that local county sheriffs are the supreme law of the land, capable of overruling federal and state laws, as well as prohibiting federal and state agencies from enforcing them—throughout rural American sheriff’s offices has often seemed like a quaint but localized problem: Sure, having set themselves up as laws unto themselves, they seem to always run their jurisdictions like private fiefdoms, but it doesn’t affect people outside those counties. But we have in fact seen—notably in the case of Klickitat County, Washington’s “constitutional” sheriff, who undermined the entire state’s ability to regulate the hunting of endangered mountain lions—that in fact their actions can have broad consequences.
