Circumstances when firearms are permitted on school property modification

SF 3572 modifies Minnesota law to clarify when authorized firearm carriers (such as permit holders) may have firearms on school property. It requires these individuals to store firearms unloaded in a locked container or trunk when not actively on duty, rather than carrying them openly. The bill defines "school property" broadly to include buildings, grounds, school buses, and facilities with posted notices, while maintaining existing exemptions for active officers and specific activities like gun safety courses. This law does not expand who can carry firearms but adds uniform storage requirements for those already permitted to carry on school grounds.
