New gun control laws are unconstitutional, say scores of sheriffs throughout the country, and they are either refusing to enforce the statutes or have signaled that enforcement will be a very low priority, The New York Times reports.

In Colorado, a law passed by the Legislature that requires universal background checks and bans ammunition magazines that hold more than 15 rounds is being challenged in a lawsuit by all but seven of the state’s 62 elected sheriffs who say it’s a violation of Second Amendment rights.

New laws in other states which were brought about as a result of the Newtown, Conn. school shootings, are also facing resistance, the Times reported Sunday.

In New York, two sheriffs have said publicly they would not enforce new gun laws, some of the toughest in the nation. In California, a delegation of sheriffs tried to convince Gov. Jerry Brown to veto gun bills that would ban semiautomatic rifles with detachable magazines and lead ammunition for hunting, according to the Times.

“All law enforcement agencies consider the community standards — what is it that our community wishes us to focus on — and I can tell you our community is not worried one whit about background checks or high-capacity magazines,” Sheriff W. Pete Palmer of Chaffee County, Colo., told the Times.
