Baltimore sues ATF for data about ‘crime guns’ that is shielded under federal law

Baltimore’s mayor is trying a new strategy to fight gun violence: suing the federal agency that traces the sources of “crime guns” but won’t share the data with local policymakers. Mayor Brandon Scott on Tuesday announced a new lawsuit against the Bureau of Alcohol, Tobacco, Firearms and Explosives, which in September denied a public records request from the city of Baltimore for gun crime data.
