A former mayor of Philadelphia who is critical of the NRA’s proposal to put armed guards in every school has been named to Sandy Hook Promise’s board of directors.  Michael Nutter served for eight years until he left office in 2016.  The board is made up in part of family members who lost loved ones on 12-14.  The nonprofit offers free gun violence prevention programs.  Nutter was added to the group in part because of his initiative to reduce violence and crime among black males.  He also serves on the Council of Criminal Justice, among other organizations.
