( KTRS ) Missouri House members are considering two Republican-sponsored bills aimed at expanding gun access at higher education institutions.

Under one measure, schools that wanted to opt out would need to staff the doors of every building with armed security and metal detectors. The second bill also has exemptions, including some sporting events and areas with grade-school children.

Supporters say students should be able to protect themselves on campus and that armed citizens with proper training can save lives during mass shootings.

University administrators criticize expanding gun access on campuses, saying it’s dangerous given binge drinking and mental health issues among college students.
