In this case the passengers are the worst witnesses...why, because they didn't know anything until after the fact. Mitchell was bothered that he wasn't getting any attention...the rest of them only looked at him once, maybe twice. that's why there descriptions differ.
If 8 people tell you a guy turned left and one thinks he went right, who do you listen too?
as Carr states, where do you draw the line...everyone can't be a suspect. the totality puts Cooper at 5' 10" -6'.
are we sure his hair wasn't red, or he had a monocle vs sunglasses..
should we throw away the description like Robert Blevins has done?
