Former Maricopa County School Superintendent Sandra Dowling says what happened to her is a case in point.
Dowling says was locked in a political battle with some members of the Maricopa County Board of Supervisors over school district funds when the sheriff's SWAT team came in the dead of night to search her home. Dowling was charged with stealing money from a school for homeless students. There were 25 felony counts in all.
"Never could I have imagined what a nightmare was waiting ahead," Dowling said.
Arpaio promised to uncover massive public corruption -- "We are looking into all avenues of this investigation," he said -- and to win a speedy conviction.
From the start Dowling maintained her innocence: "I kept saying I didn't do anything. I didn't do anything."
It took three years, but finally a judge threw out all the felony counts against Dowling. She entered a guilty plea to a single misdemeanor charge. But she said her reputation had been shattered, her career destroyed, and she owed more than $100,000 in legal fees.
"I still don't think that everybody knows I was innocent," she said.
Dowling is not alone. Arpaio has launched -- either on his own or in conjunction with the county attorney -- high-profile criminal investigations against a who's who of Maricopa County politicians and officials. The list includes the mayor of Phoenix, a former police chief, two members of the board of supervisors, Superior Court judges, and even a former state attorney general.
The charges have included public corruption, misuse of taxpayers' dollars, bribery, rape and even child molestation. What all these investigations hold in common is that they were launched with great public fanfare, but rarely resulted in convictions. Among the investigations recounted in this report, the only conviction has been on the misdemeanor charge against Dowling.
Phoenix Mayor Phil Gordon calls the sheriff's long list of investigations a "reign of terror."
Gordon came under Arpaio's scrutiny, he says, after speaking out against the sheriff's neighborhood sweeps to round up illegal immigrants.
The mayor says he received a torrent of records requests from sheriff's investigators, and he was later told that he was under investigation on possible child molestation charges. Gordon says the sheriff "bragged that he was watching my office from his office with a telescope."
The sheriff's department confirmed that Gordon was investigated on child molestation accusations. In the end charges were never filed.
"He is a coward," said former Buckeye, Arizona, Police Chief Dan Saban. In 2004 Saban challenged Arpaio's bid for a fourth term in the sheriff's office. That was when the local news reported that Arpaio was investigating his rival on charges of rape.
It was a claim made by Sabin's foster mother. She claimed the rape occurred 30 years earlier, when Saban was only 15 years old. Saban says he was the victim, not the foster mother.
Once again charges were never filed. But Saban noted the sheriff alerted the media to the details of the sordid accusation. "They put out a media campaign against me," he said. "That I was the subject of a criminal probe."
It sounds familiar to County Supervisor Don Stapley. "They indicted me on 118 counts." he said, "none of which I'm guilty of."
Those 118 counts of public corruption against Stapley made big headlines before they were thrown out of court by a judge. Arpaio has refilled many of those charges and Stapley is still fighting to clear his name.
