Did "Badge Man" Deliver The Headshot From The Grassy Knoll That Killed JFK?

The "Badge Man" is reputedly visible in Mary Moorman's fifth and most famous photo taken at the moment of the fatal shot on November 22, 1963 in Dealey Plaza, Texas. This photo has been calculated to have been captured between the Zapruder film equivalent concurrent frames of Z-315 and 316, less than one-sixth of a second after President Kennedy was struck in the head at Z-313.

In 1982 Gary Mack, the longtime curator and archivist for The Sixth Floor Museum at Dealey Plaza (the former Texas School Book Depository) first claimed to discover the "Badge Man" figure. In Mack's visual interpretation, a uniformed police officer can be seen standing behind the stockade fence, his face obscured by muzzle flash but with a badge like object on his chest.

What do you think? Is this an image of President Kennedy's assassin?
