Here is a link to Prof. Colin Miller’s site.
The Areas Of My Expertise: Alabama Federal Court Allows Expert Eyewitness Testimony Despite Eleventh Circuit Precedent.
Professor Miller discusses an 11th Circuit decision allowing expert testimony on the unreliability of eyewitness identifications. The court allowed testimony about problems with identifications, but did not allow testimony that the particular identifications in the case were erroneous.
Seems like it’s explaining things to the jury, much like the prosecution gets to introduce “syndrome” like evidence.
