The federal Bureau of Alcohol, Tobacco, Firearms and Explosives reports that in 2012 New Jersey law enforcement recovered 3,595 firearms, most in the commission of a crime, and requested that the weapons be traced to the original owner and seller.
Among these weapons were 1,943 pistols, 960 revolvers, 342 rifles, 321 shotguns, 24 Derringers, and four machine guns. The vast majority of these guns had not been used in a crime for over three years -- the average in New Jersey was 13.8 years. The biggest cohort (397) possessing these weapons was 18 to 21 years old.
Where did the guns originate? Many (425) were originally purchased in New Jersey. But other states exporting guns to the Garden State include Pennsylvania (278) North Carolina (199), Virginia (194), Georgia (152), South Caroline (134), and Florida (127). Neighboring New York, with its tough gun laws, only sent 56 of the guns to New Jersey -- only a few more than Idaho, which was the starting point for 37 weapons.
