The firearm restrictive states in the northeast love to blame others for gun violence in their states instead of facing the real problem - out of control drugs and the gangs who profit from them.
With NJ making it so difficult to buy a gun, of course the guns come from other states. This 2012 report from New Jersey shows that the guns used in crimes in NJ came from all over the USA - 47 states.
Wyoming supplied 0.1% (2 guns out of 2,112 guns used in crime!)
Of course the source of the guns is irrelevant - criminals will always find them, especially gang members who are responsible for so much of the gun violence.
