Mainly it tells me that the driver of JFK’s car pulled a .45 auto out from his shoulder holster, and discharged a hollow point slug through the foreword portion of JFK’s left temple, which caused the back of his head to explode.
It tells me many other things, but none nearly so important as that simple fact.
