When President Trump pardoned former Maricopa County Sheriff Joe Arpaio—then under contempt of court for bucking a federal injunction—he defended the action as necessary for the preservation of law and order. Lawmakers and advocacy groups expressed outrage, and for good reason. Arpaio hadn’t been a force for either law or order. Throughout his career, he repeatedly and flagrantly violated the constitutional rights of the men and women in his jails, to say nothing of his racial profiling, measures that consumed resources at the expense of actual crime in his community. Celebrated for his cruelty, Arpaio embodied a homegrown authoritarianism defined by its racism. And in shielding the Arizona sheriff from the legal consequences of his actions, Trump undermined actual rule of law, subjecting it to his whims and prejudices.
