Public school students are already required to have annual trainings to help keep them safe in case of a fire, tornado or other emergencies. The measure moving through the legislature would add firearm safety to that required list.

Firearm safety training could help “counteract some of the things that they see on TV” and in video games, Rep. Jesse Chism (D-Memphis) said during debate in the House Education Instruction Subcommittee.

The measure passed subcommittee and now heads to the full committee.
