A federal judge in Albuquerque has concluded the methods used by federal agents in a 2016 undercover sting operation made it likely they would arrest a disproportionate number of minorities. And the bureau of Alcohol Tobacco Firearms and Explosives (ATF) did nothing to avoid the potential racial bias as agents chose people to target, Senior U.S. District Judge James Parker, a Ronald Reagan appointee, wrote in a five-page order issued Monday. Parker’s ruling means Yusef Casanova, who was arrested last year, has the go-ahead to seek evidence to prove the agency targeted him at least in part because he was black. Casanova’s procedural legal victory comes as black community leaders in Albuquerque demand answers from federal and local officials about the operation. Agents arrested 103 people — 28 of whom were black, or 27 percent — a dramatic overrepresentation compared to Albuquerque’s 3 percent black population.
