Of course there is the controversy over the neck - back first wound of Pres. Kennedy. Was it a throat/neck wound that came from the angle high of the 6th floor ? Or was it actually below the neck/throat - a back wound - that had to be from a much lower angle almost even ?
The Towel Guy Shooter may indeed be the cause of the first Pres. Kennedy wound with a matching trajectory..... if so, it was captured just after he fired in the famous photo that went round the world. Notice in the full original photo those looking towards the shooter here I circled in the blow ups, and obviously as well at least a couple of the Secret Service Agents had indeed heard a shot (s ) and were turned backward and looking.
