Supporters of gun control hold a sign that reads ‘Gun Control Save Our Children’, outside the White House in Washington DC, USA, 15 December 2012. Reports state on 14 December 2012 that a gun man unleashed a hail of gunfire that killed 20 children and six adults at a school in Newtown, a quiet, affluent suburb of 27,500 people about 100 kilometres north-east of New York City. He then killed himself inside Sandy Hook Elementary School, having previously killed his mother. (Photo by Michael Reynolds/EPA)
