Charles, you're absolutely right.
Also, keep in kind, both Barbara Davis and Virginia Davis were standing at the front door watching a man with a gun cut across their front yard just moments after the shooting. They were both watching the same man as they stood practically shoulder to shoulder with each other. One said the man was wearing a light-tan jacket and the other said the man was wearing a black coat. Only a fool would believe that these two women saw two different men. Once you accept that, then it is obvious that an eyewitness can describe a jacket differently than another eyewitness even though both were looking at the same jacket. Therefore, their point is entirely moot.
It happens all the time. But our conspiracy advocate friends around here would have everyone believe that every single eyewitness should give the exact same description as each other or else something is amiss. It's pure foolishness.
When five people watch a car crash, you'll get five different stories about what happened. That's to be expected as not everybody pays attention to the same details.
When two people see a man for merely seconds, it is IMO, although not completely impossible, highly unlikely they can both identify the same man, when they can't even agree on the color of a jacket. Benavides saw the killer much better and was still unsure he would be able to identify the man. I have been in his position, several years ago, when I saw a robbery happening right in front of me. Everything happened very fast and although I thought I had seen the man clearly enough, when police brought a man they had arrested back to the scene, I couldn't say for sure that it was the same man.
Yet, in this case we are to believe that all the witnesses who attended the line up were able to actually identify the same man? Talk about pure foolishness.
