Guns in the hands of those with a criminal record are often prohibited by federal law.
But when a state doesn’t have a concealed carry statute, that law is often enforced by the state police.
The New York City Police Department, for example, has been using its authority to enforce the law since 2010.
The department is charged with enforcing the laws that state police enforce.
In 2016, it was sued by the NRA over its enforcement of the city’s concealed carry ordinance.
The city of New York, for its part, is now asking a federal judge to issue an injunction to prevent the NRA from enforcing the law on its own.
The suit comes in the wake of New Yorkers being forced to take an armed security posture after a gunman opened fire at a movie theater in the heart of the boroughs biggest city.
The gunman, identified by police as James Hodgkinson, a former member of the Republican Party, killed four people and wounded five others before being killed by police.
He had a long criminal history and was on probation for domestic violence.
The NRA filed the lawsuit last year after New York Mayor Bill de Blasio took the first step toward cracking down on the use of guns in the city.
In June, the city issued a series of ordinances that allow licensed gun owners to carry concealed weapons in public places, including restaurants, schools, bars, and shopping centers.
The NYPD was allowed to use the ordinances as part of its plan to improve public safety.
De Blasio and his police commissioner, William Bratton, said that while the mayor is committed to improving the safety of New Orleans residents, he has no intention of infringing on the right of the Second Amendment right of law-abiding citizens to own guns.
But the NRA sued the city in the federal court in New York for violating the Second and Fourth Amendments.
It’s not clear whether the city plans to appeal.
