I have shared similar concerns through this blog. I will provide links to my commentary as well.
1. Eyewitnesses are highly reliable. This belief is so much part of our culture that one often hears talk of a “mere” circumstantial case as contrasted to a solid case based on eyewitness testimony. In fact, research shows that eyewitness identifications are highly unreliable, especially where the witness and the perpetrator are of different races. Eyewitness reliability is further compromised when the identification occurs under the stress of a violent crime, an accident or catastrophic event — which pretty much covers all situations where identity is in dispute at trial. In fact, mistaken eyewitness testimony was a factor in more than a third of wrongful conviction cases. Yet, courts have been slow in allowing defendants to present expert evidence on the fallibility of eyewitnesses; many courts still don’t allow it. Few, if any, courts instruct juries on the pitfalls of eyewitness identification or caution them to be skeptical of eyewitness testimony.
