The national media, much less diverse and fragmented in 1963 than today, joined the campaign to assuage doubts and dispel “rumors” about JFK’s assassination. Pollsters were already finding that a majority of Americans suspected conspiracy. Life Magazine’s Dec. 6 issue was devoted primarily to photo coverage of the Kennedy funeral, but also included a piece by Paul Mandel entitled “End to Nagging Rumors: The Six Critical Seconds.”
The article began with a quote from Dallas DA Henry Wade: “I would say without any doubt that he is the killer”, and referred to Oswald as “the assassin.”
Life Magazine had earlier purchased rights to Abraham Zapruder’s famous home movie of the murder in Dealey Plaza, and in a November 29 issue had shown frames from that film in black-and-white. Now the Mandel article tried to reconcile the film with Oswald’s guilt.
