Yep. I said way back when that Mangum's race-baiting backers will determine which of the boys come from money. Then all they need are names and photos, readily available - plastered everywhere - and, perhaps even with Kim's help, pick out two or three who they sort of remember were there.
It sounds like they misfired in at least one case, and that misfire will taint the identification of the other one who doesn't have an alibi.
Has anybody stated whether either of the chosen players are in any of the photographs?
One reason the stripper may be holding back on fingering the third kid is that her team is hoping the defense will publicly release the photos.
That way, they can figure out which kid is helping her into the car and ID him, thus avoiding another missed shot in the dark.
