Dangerous weapons in public libraries prohibition

SF 471 prohibits possessing dangerous weapons in public libraries under Minnesota law. It makes unauthorized possession a felony punishable by up to five years in prison or a $10,000 fine, while allowing licensed firearm permit holders to carry weapons (as a misdemeanor) and exempting licensed peace officers. The bill amends Minnesota Statutes section 609.66 and applies to crimes committed on or after August 1, 2025. It directly affects library patrons, staff, and law enforcement by defining legal boundaries for weapon possession in public library buildings.
