State Attorney General Gurbir Grewal is speaking out against the pro-Second Amendment resolutions sweeping through conservative parts of New Jersey.

Grewal, the state’s top law enforcement official under Gov. Phil Murphy, said he is troubled by “more extreme” versions of the non-binding resolution in which some municipal councils, and at least one county freeholder board, have endorsed a “sanctuary” for the Second Amendment.

“My primary concern is not that law enforcement officers in New Jersey will stop enforcing firearm safety laws," Grewal, who was appointed, said in a letter to all 21 county prosecutors provided to NJ Advance Media.

“My real concern is that these so-called ‘sanctuary’ resolutions will confuse otherwise law-abiding residents, who may incorrectly believe that they no longer have to comply with firearm safety laws, including carry laws and prohibitions on assault weapons, ghost guns, or large-capacity magazines,” he added.

“This confusion can create serious risks for law enforcement and the public at large, with potentially deadly consequences. As we work to end gun violence across New Jersey, it is especially important that we make clear that our state’s firearm laws remain fully in effect,” Grewal continued.

In response, National Rifle Association board member Scott Bach defended the resolutions and alluded to Murphy, a Democrat who has signed into law additional gun control measures.

“Leave it to the Murphy administration to find a way to object to towns vocalizing their support for the Second Amendment,” Bach, executive director of the Association of New Jersey Rifle & Pistol Clubs, said when contacted by phone Saturday.

New Jersey’s first pro-Second Amendment resolution was adopted in December by the West Milford council. It declared the rural Passaic County municipality a “Second Amendment/lawful gun owner sanctuary township," mimicking the provocative word choice on numerous pro-gun resolutions in Virginia and other states.

The Cape May County freeholder board approved a pro-Second Amendment ‘sanctuary’ resolution on Jan. 14, two weeks before President Donald Trump, a Republican, held a campaign rally in Wildwood.

However, most places have steered clear of calling themselves a sanctuary, a play on jurisdictions using the same term to express support for undocumented immigrants in their communities . The freeholder board in Monmouth County approved a resolution on Thursday night declaring Monmouth a “Second Amendment/Lawful Gun Owner County."

Grewal emphasized that the resolutions — regardless of the wording — provide no leal authority on gun laws, or anything else.

“It goes without saying that local and county officials are free to express their views on state and federal policies. What they may not do, however, is prevent law enforcement from enforcing validly enacted and generally applicable statutes,” Grewal said in his letter.

Some of the resolutions have condemned “red flags laws” allowing a judge to order the removal of weapons from someone judged a threat to themselves or others.

New Jersey’s red flag law took effect in September, with nearly 200 guns seized as of Jan. 22, and has been a rallying cry for gun control opponents.
