Of the 216 witnesses who were interviewed by the FBI or the Warren Commission, 73 of them were Dallas Police Officers,
Dallas Deputy Sheriffs, Secret Service Agents and other government employees who traditionally tend to identify with
the government’s case. Thus, the tabulation of 216 witnesses (culled from the Warren Commission’s 26 Volumes and from
Commission Documents stored in the National Archives) does not constitute a random sample of the witnesses to the
assassination. Hence, it cannot be the basis for an accurate statistical analysis of witness accounts. What happens if
we separate out the 73 government employees from the 143 nongovernment employees?
