The Justice Department has issued a scathing report accusing a prominent Arizona sheriff of widespread discrimination and civil rights violations against Hispanics and unlawful retaliation against critics who spoke out in opposition. On Thursday, federal investigators said Sheriff Joe Arpaio of Maricopa County targeted Hispanic residents, illegally detaining and then denying them basic rights behind bars. The findings could subject Arpaio to court-ordered reforms. He is also currently under criminal investigation by a criminal grand jury in Phoenix. On the heels of the report, the U.S. Department of Homeland Security has announced it’s cutting its ties with Arpaio, including the suspension of programs under which undocumented immigrants are handed over to federal authorities for deportation. The report comes at a time Arpaio has recently faced growing calls to resign following mounting evidence his police department neglected scores of sex crimes.
