OK ....Let's go with the percentage..... 80% of the witnesses reported only one man was the shooter.....
Bull. Only one witness saw a shooter at all.
How could anyone possibly know they saw the same person Markham or Davis saw? They saw the gun in his hands..... How many men were at the scene or trotting up Patton carrying a gun?
How should I know? Seeing a guy holding a gun (or in some cases not even holding a gun) at a different location is not the same as seeing a shooter.
