Tim,
Good advice. Doing ten at a time will make it much easier to both post and discuss/debate.
One of the many interesting things about the witnesses to the JFK assassination is the evolving nature of many of their statements. Some witnesses originally made statements and even gave testimony which was opposite to the WC conclusions. Then over time they began to think they were mistaken and came to accept they must have been wrong. This is not an indication of something necessarily sinister or conspiratorial. The Newman's and Sam Holland are good examples.
While there is indisputable evidence from dozens of witnesses to the assassination that they were threatened or intimidated in an effort to get them to change their statements, still others appear to have changed their minds about what they saw and heard as a result of the psychological phenomena of cognitive dissonance.
Cognitive dissonance is the mental discomfort or psychological stress that comes from simultaneously holding two or more contradictory beliefs, ideas, or values. The occurrence of cognitive dissonance is a consequence of performing an action which contradicts widely held beliefs, ideals or values; and also occurs when confronted with new information that contradicts previously beliefs, ideals, and values.
