Richard Mack

Richard Mack is a former sheriff of Graham County, Arizona, and the founder of the Constitutional Sheriffs and Peace Officers Association (CSPOA). He is best known for his role as a plaintiff in a landmark Supreme Court case that established important limits on federal power over local law enforcement.

In 1997, Mack won his case before the U.S. Supreme Court challenging provisions of the Brady Handgun Violence Prevention Act that required local sheriffs to conduct background checks. The Court's ruling in Printz v. United States (with Mack as a co-plaintiff) established that the federal government cannot commandeer local law enforcement to enforce federal regulations, an important Tenth Amendment precedent.

Following his Supreme Court victory, Mack founded CSPOA to educate sheriffs and peace officers about constitutional principles and their role as the last line of defense for citizens' constitutional rights. The organization promotes the idea that sheriffs have both the authority and duty to refuse to enforce unconstitutional laws.

Mack has authored books on constitutional law and the role of sheriffs, and speaks widely on these topics. He appeared on the Kim Monson Show in September 2022 to discuss the constitutional sheriff movement and his Supreme Court victory.
