NEW ORLEANS (AP) — Federal officials say they have begun a comprehensive review of the scandal-plagued New Orleans Police Department.

It’s a probe that the city’s new mayor Mitch Landrieu asked for, and one that Landrieu predicted will result in court-supervised transformation of the department. Landrieu was joined at a news conference Monday by two members of the U.S. Justice Department’s Civil Rights Division.

Assistant Attorney General Tom Perez said the investigation will include lawyers and non-lawyers with broad experience in police issues. He said the probe will be independent of ongoing federal criminal investigations, including a probe of the shooting of unarmed citizens at the Danziger bridge in the chaotic aftermath of Hurricane Katrina.
