This bill allows colleges to join the school guardian program and appoint trained, armed staff for campus safety. It permits certain employees and students to carry handguns on campus if they meet requirements like holding a concealed carry permit. The bill establishes a felony for firing a weapon within 1,000 feet of a school (with exceptions for self-defense) and requires arrested individuals to be held until a judge sets bail. Colleges must also promote a tip-reporting app, provide active shooter training to staff and students, post mental health resources, form threat assessment teams, conduct annual security checks, and transfer safety and threat data.
