During live broadcasts there's always the chance that something will happen that producers can't control. As CNN's Chris Cuomo was reading off the names of the police officers that were killed or shot in Baton Rouge, some idiot heckled them and yelled very clearly "CNN is the devil!"
He was as loud as Chris Cuomo, and as the CNN host was trying to give viewers a rundown about the attack, he yelled, "The system is oppressive. That is the issue. That is the entire issue."
Cuomo tried to make believe the person wasn't there, but the mics were very sensitive. "We must be a melting pot if we're are going to survive."
Unfortunately the heckler continued into the next segment until it appeared CNN gave up on live broadcasting and Anderson Cooper took over from the studio.
