An 18-year-old who survived the classroom shooting at Umpqua Community College on Wednesday criticized Ben Carson's comment that the shooting victims could have attacked the gunman. "I'm fairly upset he said that. Nobody could truly understand what actions they would take like that in a situation unless they lived it," Mathew Downing told CNN via Facebook. Carson, a Republican presidential candidate, said on Fox News after the shooting in Oregon that he would've done more to prevent the gunman from going on a killing spree. "Not only would I probably not cooperate with him, I would not just stand there and let him shoot me," Carson said. "I would say, 'Hey guys, everybody attack him. He may shoot me, but he can't get us all.'"
