Riot reporter: 'I felt like I was a foreign correspondent again'

CNN national security correspondent Alex Marquardt relives the harrowing moment when a mob "turned" on his crew. "I felt like I was a foreign correspondent again and it was shocking to see this happening in my own country, in the city that I live in, just two miles from my house," he says. But "I really do think that this is a reflection of where we are right now... The division, the tribalism, the sectarianism, those are words that we use when we cover other countries as foreign correspondents."
