The New Hampshire attorney general's office is preparing to offer guidance to police over a new gun law that aims to constrain their ability to help with the enforcement of federal gun laws.While Democrats are raising concerns about "nullification," Attorney General John Formella said he believes the law doesn't go that far.Republicans in Concord said they wanted a bulwark against federal overreach on firearms regulation when they passed House Bill 1178 this year. The legislation prohibits state officials from doing anything to help enforce federal gun laws that are incompatible with state law.On Wednesday, Formella told the Executive Council the new law might not be as sweeping as some believe."The law is narrower, I think, than it's been reported," he said. "It doesn't try to say that federal firearms laws aren't enforceable in New Hampshire or in effect in New Hampshire, it just deals with what state and local agencies can do to cooperate and assist with the federal government in enforcing those laws."Already facing questions about the law, the attorney general's office issued a memo Wednesday saying it's working on guidance for local law enforcement that now has to make sure before officers enforce or cooperate on a federal case that state law lines up with "...any federal law, regulation or executive order regarding the regulation of firearms, ammunition, magazines or the ammunition feeding devices, firearm components, firearms supplies or knives." Democrats said the law could hinder the implementation of any expanded background checks or new red-flag legislation that might pass in Washington. "Ninety percent of the citizens of our country believe there should be universal background checks, and we should be doing them here in New Hampshire," said Executive Councilor Cinde Warmington.Gov. Chris Sununu said he doesn't anticipate significant conflict between state and federal gun laws or problems for local law enforcement."We feel very confident about the law as it moves forward, but the attorney general always reviews laws that have any impact with the federal government, just to make sure we're dotting the 'I's and crossing the 'T's, but so far, we're very confident that as we move forward, the federal laws are the federal laws, and the state laws are the state laws," Sununu said.
