The districts that contain Chicago, Los Angeles and New York City ranked last in terms of federal gun law enforcement in 2012, according to a new report from Syracuse University’s Transactional Records Access Clearinghouse, which tracks federal data.

Federal gun crimes include illegal possession of a firearm in a school zone, illegal sale of a firearm to a juvenile, felon, or drug addict, and illegal transport of a firearm across state lines. In Chicago, the majority of gun charges last year were for firearms violations.

The districts of Eastern New York, Central California, and Northern Illinois ranked 88th, 89th and 90th, respectively, out of 90 districts, in prosecutions of federal weapons crimes per capita last year, but it wasn’t always this way. All three districts fell lower on the list than they had been in years past. In 2010, for example, Chicago was 78th in federal weapons prosecutions.
