U.S. sheriffs are encouraged to act as shield against federal tyranny.

The 100 or so sheriffs gathered in a Las Vegas hotel ballroom two weeks ago learned that some weighty titles have been attached to the stars they wear on their chests. 

"Ultimate enforcers of the Constitution." "Protectors against government tyranny." "America's last hope." "Brave oath keepers."  
And the sheriffs, including eight from Colorado, learned that they need to protect their citizenry from much more than local lawbreakers. In today's world, public enemy No. 1 just might be the federal government — or the "out-of-control federal bureaucracy," as organizers of the convention like to refer to it. 
The person who will "stand tall against federal tyranny," even if it means armed resistance, according to organizers, is the county sheriff. 
The Constitutional Sheriffs and Peace Officers Association's inaugural convention was designed to be the national coming-out for this idea and the start of an educational movement that its founder hopes will sweep the country.
Former Graham County, Ariz., Sheriff Richard Mack wrote a book, "The County Sheriff: America's Last Hope." In it, he asserted that sheriffs have the supreme law enforcement power in their counties under the Constitution and the 10th Amendment. Much of what federal agents are doing in counties is unconstitutional, he wrote. Federal agents have no authority beyond policing treason, piracy, treaty violations and counterfeiting.
Thus, the scofflaws that sheriffs might encounter today — and who should be run out of town by a SWAT team, if that's what it takes — include agents for the U.S. Forest Service; the Bureau of Land Management; the IRS; the FBI; the Bureau of Alcohol, Tobacco, Firearms and Explosives; the Environmental Protection Agency; and even the Food and Drug Administration.Online Constitutional Sheriffs materials state, "The sheriff's position overrides any federal agents or even the arrogant FBI agents who attempt to assume jurisdiction in our cases."
