Nashville shooting sparks calls for increased school security and political turmoil.

Tennessee Governor Bill Lee plans to expand a school safety measure to include the placement of school resource officers at every school in the state following the recent shooting at a private Christian school in Nashville. The governor's plan would expand a proposal to place an armed guard, otherwise known as a school resource officer, at every public school in Tennessee and offer state funding for private schools to hire an armed guard. The new plan would also seek additional mental health support through school-based behavioral health liaisons.
