More guns from out of state are being used to commit crimes in New York City, officials said Wednesday.
In 2011, 90 percent of the 2,433 traceable guns used in city crimes were from outside New York state, including 237 from Pennsylvania, said Mayor Michael Bloomberg.
The year before, 86 percent of the 2,319 guns came from out of state.
Even though New York has strict gun laws, Bloomberg said the city is at the mercy of weak national and state laws.
It's too easy to carry a gun from one state to another, said Bloomberg, noting that most of the guns come from, in addition to Pennsylvania, Virginia, North Carolina and South Carolina.
"The reality is laws in states across the nation and in Washington, D.C. have a real impact on the safety of New Yorkers," Bloomberg said.
Bloomberg, an outspoken advocate for gun control, said he will keep fighting to get laws changed.
"Our top priority is keeping New Yorkers safe and that includes reducing the flow of illegal guns into our city," Bloomberg said.
In 2006, New York City filed a federal lawsuit against 15 out-of state gun shops, including one in Berks County and another in Monroe County, claiming that criminals were buying the guns illegally in those shops and taking them into New York.
Another lawsuit filed by the city later the same year made the same claims against 12 additional out-of-state gun shops, including one in Northampton County.
Both suits sought supervision and extra training for gun dealers.
