On Sunday night, NBC host Megyn Kelly promoted an upcoming interview with Alex Jones. It only took a few minutes for outrage to build. Through his radio show, YouTube page, social media accounts and the website InfoWars, Jones has helped spread false or unproven theories.

And how should mainstream media react when theories that appear on Jones' website inspire an armed gunman to walk into a family pizza parlor?
