Tennessee lawmakers approved a bill allowing teachers and staff to carry concealed handguns in schools, prompted by a tragic shooting. The bill requires training and approval by school officials, but parents and most employees would not be notified. Supporters argue that armed staff would protect students and act as a deterrent, especially in rural areas. Critics fear increased danger and protest that more guns in schools risk children's lives. The legislation passed despite opposition, and now awaits the governor's approval, likely becoming law. This move follows similar actions in other states after mass shootings, with ongoing debates over safety, responsibility, and the potential risks of having firearms on school campuses.
