Training teachers to carry guns in school | The National Documentary

A group of teachers in Arlington, Texas are getting trained to carry a gun in their classrooms, so that if a gunman ever comes to their school they'll be ready to protect their students. The National Documentary takes us inside a course that's arming teachers — an idea that appears to have the support of U.S. President Donald Trump.
