He was not surprised by the new North Carolina numbers but is concerned with the cases not being reported to police -which he said happened "quite a bit" while he was sheriff."We've got to support our teachers more. They're afraid sometimes to say anything; afraid they're going to violate somebody's rights or get in trouble; that somebody's going to say they've got a bad school because they reported a gun on campus or drugs in school," Harrison said.The North Carolina Association of Educators is pushing to make schools safer with more teacher support, more mental health workers in schools, and lessons about students' civic responsibility.
