After spring break, teachers, custodians and more will be carrying concealed weapons at school through the new "Guardian program." Hall, who co-authored campus carry, now wants to broaden the law to K-12 classrooms. His bill - which, as of March 10, had yet to be heard in committee - would allow licensed Texans, such as parents and teachers, to carry concealed handguns throughout public schools and open enrollment charter schools. "Schools, known as a gun-free zone, might as well hang a neon sign saying, 'If you want to harm kids, come in here,'" Hall, R-Edgewood, said in an interview. "The more people there are who can protect, the safer our society is."
