Gov. Greg Gianforte on Friday signed a bill that prohibits state and local law enforcement in Montana from enforcing federal bans on firearms, ammunition and magazines.
Supporters of the law have said it would protect the Second Amendment from stiffer gun control laws that could come from federal legislation or executive orders by President Joe Biden in the wake of several mass shootings that took place this year, including a shooting last week that killed eight people in Indianapolis.
Opponents of the bill have said it would make it difficult for local law enforcement to collaborate with federal authorities on issues beyond gun access when such collaboration is essential to protect public safety, including in cases of domestic violence and drug offences.
Montana law would prohibit law enforcement officials and other state employees from enforcing, implementing or spending state funds to uphold federal bans on particular kinds of firearms, ammunition and magazines.
