St. Louis County Prosecutor Bob McCulloch, before announcing that Darren Wilson would not be indicted, scolded the media for its coverage of the shooting death of Michael Brown. 

“The most significant challenge encountered in this investigation has been the 24-hour news cycle and its insatiable appetite for something, for anything to talk about, following closely behind with the non-stop rumors on social media," he said. 

Howard Kurtz, host of "Media Buzz," agreed with McCulloch on "Happening Now" today, saying many media outlets ran with the faulty narrative of "unarmed black man shot in cold blood by overzealous cop."

Much of it was based on eyewitness accounts that were later found to be untrue or disputed by other witness accounts.

"We did know the evidence but that did not stop a lot of people from going on TV and fanning the flames," said Kurtz.

Kurtz also criticized local authorities for shrouding the investigation in secrecy, pointing out that "we didn't know until very late in the game that there had been a struggle in the car, that the gun had gone off." 

He said the media could have done a better job with more information, but is still at fault for putting out a "one-sided narrative." 

Heather Nauert noted that so much false information was put out on social media and many people still repeat these "falsehoods."

"It's very hard to change the story once that initial version gets out. It kind of gets hardened into cement," he said.
