WASHINGTON (AP) — The Justice Department’s internal watchdog on Wednesday faulted the agency for misguided strategies, errors in judgment and management failures during a bungled gun-trafficking probe in Arizona that disregarded public safety and resulted in hundreds of weapons turning up at crime scenes in the U.S. and Mexico.

A former head of the department’s Bureau of Alcohol, Tobacco, Firearms and Explosives and a deputy assistant attorney general in Justice’s criminal division in Washington left the department upon the report’s release — the first by retirement, the second by resignation.
