While the Supreme Court may soon decide a case affecting local gun control measures, a large coalition of city mayors is calling on Congress and the federal government to take action to curb illegal weapons sales. Mayors Against Illegal Guns, a bipartisan group of 450 mayors, wants the Obama administration and lawmakers to get behind dozens of proposed reforms, including tougher enforcement of laws at gun shows and the creation of a federal interstate firearms trafficking unit. Many of the changes sought by the mayors focus on the Bureau of Alcohol, Tobacco, Firearms and Explosives (ATF), whose agents have been “undermined by congressional restrictions, inadequate resources, and a lack of leadership from federal officials in Washington,” according to the group’s report.
