Indiana lawmakers are pushing to make their state the first in the nation to require every school to have an armed employee on site, a proposal that aligns with recent recommendations from a National Rifle Association study.

The proposal in Indiana advanced through a House committee Tuesday. It goes beyond a law signed last month in South Dakota that would allow — but not require — teachers to carry guns.

The Indiana bill would mandate that one officer in every public and charter school have a loaded weapon during school hours. The officers could be police officers or other non-educators but also could be teachers or principals.
