Did you read the article ?
Yea, it's stating that Montana won't cooperate with federal agents who request info on brace owners.
It's a misleading title since the ATF can still roll up to someone's house, shoot their dog, sprinkle crack on it and take the brace owner to prison for 10 years.
I wouldn't be surprised if they actually did help the feds with anything and everything they want since politics is all fake and gay in 2023.
