The mayor of Dayton, Ohio, Nan Whaley, has revealed that police got to the scene of the mass shooting in Dayton and killed the gunman in less than one minute. The attacker killed nine people and injured at least 26 in that time. 'Hundreds of people in the Oregon district [of Dayton] could be dead today,' Whaley said. 'The question has to be raised: why does Dayton have to be the 250th mass shooting in America … this year?'
