Guns in bars. Guns in airports. Guns in day care centers and sports arenas. Conservative state lawmakers around the country are pressing to weaken an array of gun regulations, in some cases greatly expanding where owners can carry their weapons.

But the legislators are encountering stiff opposition from what has been a trusted ally: law enforcement, the New York Times reports.

In more than a dozen states with long traditions of robust support for gun ownership rights, and where legislatures have moved to relax gun laws during the past year, the local police have become increasingly vocal in denouncing the measures. They say the new laws expose officers to greater danger and prevent them from doing their jobs effectively.

“We are a gun society and we recognize that, but we should be writing gun laws that make us safer,” said Leonard Papania, the police chief in Gulfport, who opposes part of a new state law that creates exceptions to the rules for concealed-carry permits. “Do you want every incident on your street to escalate to acts of gun violence?”

Mississippi’s measure, signed into law in April and pushed mainly as an effort to allow worshipers in church to arm themselves, is one of several that have passed in recent months. West Virginia and Idaho have approved laws allowing people to carry concealed handguns without a permit or firearm training — and, in many cases, without a background check. Texas has given residents the right to carry handguns openly. Oklahoma appears set to pass a similar measure in the next several weeks.
