For years, the Justice Department has investigated Sheriff Joe Arpaio of Arizona. In December, the department accused Arpaio of violating the civil rights of Hispanics for unlawfully stopping, detaining and arresting them. Then, for months, Justice officials tried to negotiate a settlement. In April, when negotiations fell through, the department threatened to sue. […]

The Justice Department announced Thursday that it has sued Arpaio, his office and Maricopa County for civil rights violations, including what it says is the long-standing racial profiling of Latinos.

“At its core, this is an abuse of power case involving Sheriff Arpaio and a sheriff’s office that disregarded the Constitution, ignored sound police practices and did not hesitate to retaliate against perceived critics in a variety of unlawful ways,” said Thomas E. Perez, assistant attorney general for the Civil Rights Division, at a press conference in Phoenix where the lawsuit was filed.
