Review title: This Fraud Should Bear The Caution: Pro-Government Propaganda Product review: ABC News anchor Peter Jennings endorses, as the absolute and definitive truth, the 1964 Warren Commission Report that concluded Lee Harvey Oswald alone assassinated President Kennedy - notwithstanding the Report is discredited and over 70% of Americans believe there was a conspiracy. Jennings' purported proof: a computer simulation by an amateur technician, Dale Myers, who created a 3D interpretation of Abraham Zapruder's famous 8mm home movie of the murder using Dealey Plaza's topography. When the notorious Allen Dulles ran the CIA in the 1950s, he created "Operation Mockingbird" to massively infiltrate and manipulate the U.S. news media. Jennings succeeds only in unmasking himself as a high-profile mockingbird.
