From MSNBC.com and the wire services:
Arizona sheriff violates civil rights of Latinos, Justice Department says
The U.S. Justice Dept has released a report accusing Maricopa County Arizona Sheriff Joe Arpaio of violating the civil rights of Latinos. NBC's Pete Williams has the details.
Updated at 5 p.m. ESTThe U.S. government said Thursday that the man who called himself the toughest sheriff in America ran an office that has committed wide-ranging civil rights violations against Latinos, including a pattern of racial profiling and heavy-handed immigration patrols based on racially charged complaints.
The U.S. Justice Department's expert on measuring racial profiling called it the most egregious case he has seen, the department's civil rights division chief told reporters.
The scathing report on Maricopa County Sheriff Joe Arpaio, obtained by The Associated Press ahead of its release, marks the federal government's harshest rebuke of a man who rose to national prominence for his immigration crackdowns. Republican presidential candidates have competed for his endorsement.

Maricopa County, Ariz., Sheriff Joe Arpaio is accused by the Department of Justice of committing wide range of civil rights violations against Latinos.
Arpaio has long denied the racial profiling allegation. His office did not immediately respond Thursday to requests for comment.
After the report was released, the Department of Homeland Security announced it would cut ties with Arpaio.
Secretary Janet Napolitano, formerly Arizona's governor, said the department is ending an agreement with the Maricopa County sheriff's office that allowed trained deputies to enforce immigration laws. It's also restricting the office's use of the Secure Communities program, which uses fingerprints collected in local jails to identify illegal immigrants.
