You know my theory, but let me repeat it (humor me).
People administering IDs can convey things even unintentionally. We all learned how to read non-verbal language before we read or spoke sentences.
With this bunch it's easy to believe it was overt and intentional, but it didn't have to be.
I think the Investigators, the same guy administering the photo lineup, thought the bunch of them was lying. There was a wall of silence. Even though they had been threatened and rattled - the 18 and 19 years olds held firm in the face of adversity. I think the investigators (they ALWAYS have a theory) most likely thought the 23 old uniamiously voted as Team Captain - David Evans - was one of the only guys the could keep them all in line. So, either they thought he was holding them together or they may have thought if Evans was facing charges and pressure was brought to bear on him, he may back off on the flock or cave and bring the whole thing down like a house of cards.
It's only a theory, but I do know how the media works. Most of these media people run with theories given to them off-the-record or hinted at during a supposed hypothetical conversation. I don't think it was a coincidence that Geraldo was on National TV with O'Reilly saying that the week of the indictments he expected the soft white boys to run to the DA to get plea deals to avoid 20 year sentences.
I think someone on the Prosecution side of house was floating those theories and it also explains why the media was also so sure the team was guilty. Ostensibly they were not going to run and plead to crimes they didn't commit.
How many times has a Doctor or Nurse asked you questions during or after a test and you KNEW from the question or their reaction there was a problem with the test?
If the prosecution thought this was the guy, they could've easily telegraphed it before the offical lineup process. If I keep asking you questions about one guy and keep showing you his picture. It doesn't take long to pick up on the fact that you have suspicions about that guy.
I like the coughing cop scenario. That's got my vote.
I think it's just too coincidental that the ones sher chose are all rich and she couldn't ID any of them a week after the alleged event but could two weeks thereafter.
Follow the money.
