CBS LAS VEGAS- U.S. Congressman Steven Horsford, from District 4, talks about the speech he gave on the floor of the State Assembly. A group associated with and funded by the National Rifle Association (NRA) is pushing its own proposal for reducing mass shootings in schools, unveiling Tuesday a 225-page “school safety” report that recommends sending a trained, armed officer to every school in America, as well as various “layered security” measures it says will make schools safer. Do you agree with the National Rifle Association’s proposal to train and arm staff in all schools? Callers tell us if they agree with the National Rifle Association.
