This bill would repeal several Michigan firearm and weapon laws, including restrictions on concealed weapons. It updates exemptions for peace officers, corrections staff, military members, and licensed individuals, and changes rules for carrying firearms on school property. Certain people, such as concealed pistol license holders or those with school permission, could carry firearms in specific situations. The bill also reduces some penalties, allows exceptions for transporting unloaded or antique firearms, and requires training for corrections workers who carry stun devices.
