"The sheriff comes from the people, and serves the people," Wilson says. "The sheriff is directly responsible to the people … and the public has the duty, and ability, to reaffirm their faith in the sheriff."
But a sheriff's specific duties differ from state to state. All U.S. states except Alaska and Connecticut have sheriffs. Each state constitution mandates the sheriff's position and outlines the rights and responsibilities of the officeholder. In general, sheriffs are elected officials, charged with a specific set of duties. They oversee law enforcement activities in the jurisdiction, operate the jail, and provide security at county courthouses. In some states, the office is also charged with transporting mentally ill persons to appropriate care facilities, enforcing laws concerning diseased livestock, or other obscure duties.
In many places, the county sheriff's office has taken a back seat to fast-growing municipal law enforcement agencies. In other communities, the sheriff is one of the most powerful, popular politicians in local government, hobnobbing with the likes of governors and U.S. congressional representatives.
In Wisconsin, Milwaukee County Sheriff David A. Clarke Jr. chose to take his office in the latter direction. His outspoken manner coupled with his visible presence in conducting arrests and other high-profile activities within city limits dismayed administrators in some municipal police agencies. But Clarke says his method was generally embraced by officers at the street level and, most importantly, by the voters.
"I felt there was a lot that a sheriff could do to make a difference," says Clarke, who has held the office since March 2002. "[Members of the general public] just want to be kept safe. They don't care who's doing it."
