Right now, anyone writing a book or making a documentary about the AA case has to deal with the fact that experts testifying in the AA case, and experts as recently as ten years ago, found a match between AA's and AN's ear.
One approach for an author or filmmaker is to attempt to show that ear id is unreliable. We should know whether or not this is the case fairly soon: researchers in the UK are working on this issue, there is an EC project (see fearid.com) in the related area of ear prints, and new biometric technologies are being developed. There is increased support for these efforts because of the potential benefits in apprehending terrorists.
Another approach is to explain that the experts were working with older methods and technologies. I think, at this point, that that is the most reasonable explanation for why the ear evidence conflicts with the DNA evidence.
Yes but I believe the suggestion, by you, was that AN is AA or visa versa which means to me that AN's ear was injured and changed into what AA's ear ended up being. right?
I did not mention AN, nor did I mean to imply anything re AN. My apologies for poor phrasing and bad word choice. For what it's worth, here is my original post:
"The top of AA's right ear shows the results of injuries, like a boxer's cauliflower ear; this is consistent with the shattered right side of her jaw and a finger-width groove, probably caused by a grazing bullet wound, behind her right ear."
We know that experts, as recently as 1995, found a match between AA and AN. Most of the experts concentrated on the shapes and/or measurements of the inner part of the ear.
>If AA had a bullet wound behind or in front her ear
All descriptions of this scar identify it as behind the ear. There is no conflicting evidence about its existence, position or its general appearance.
>Seriously, AA's ear looks too natural to be the end result of any injury
I don't know if I agree or disagree at this point. I'll know a bit more when the Computer Vision article is published.
So far in my reading, the mathematical curve of the shape of the outer part of the ear is derived from a relatively small number of nodal points, or vertices. I'm guessing that's probably 6-8 points, and not more than 10 points. The curve of the outer part of AA's right ear appears to require more points, or specific changes to the tangency or weight of the points, depending on which type of curve being used. That is, if you were modeling AA's ear on a computer, you'd have to add points or tweak points to a template model. But again, that's only what I've been able to find out so far.
