FILE - In this April 18, 2013 file photo, community gun safety advocates and members of the public hold signs during a rally and vigil to honor victims of gun violence, sponsored by Colorado Ceasefire, on the steps of the Colorado State Capitol, in Denver. When a gunman opened fire inside a packed movie theater in July of 2012, killing 12, it helped revive the national debate over gun control.
