Let me provide just one example of this phenomenon. It involves the autopsy that the military conducted on the body of President Kennedy on the very evening of the assassination.

Beginning in the 1970s, a team of Navy enlisted men began telling a remarkable story. They said that on the evening of the autopsy, they had carried President Kennedy's body into the Bethesda Navy Hospital morgue in a cheap shipping casket.

Why was this a problem? The president's body had been carried into the morgue at 8 p.m. by a military color guard consisting of members of the various armed forces, not by a team of sailors. Moreover, at the 8 p.m. entry, the body was inside the heavy, ornate casket into which the president's body had been placed at Parkland Hospital in Dallas. The autopsy officially began at 8:15 p.m.
