As the National Rifle Association pushes for armed guards in every school, “Democracy Now!” hosted an on-air debate over what type of security measures should be taken in schools to prevent future tragedies. Featured guests included Sean Burke, president of the School Safety Advocacy Council; and Damon Hewitt, an attorney with the NAACP Legal Defense and Educational Fund and co-author of “The School-to-Prison Pipeline: Structuring Legal Reform” (NYU Press 2010).
