Many people have poor face recognition. My wife has a hard time recognizing actors when the dress and act differently than she is used to. I am sure there is an element of racism when suspects are falsely identified by white victims. On some level they think that black people are dangerous and that the person they pick in the lineup must be guilty of something; that and an innate desire for revenge and the desire to reduce their feeling of powerlessness. This is unfortunately encouraged by ambitious law enforcement officials.
I however am very good at facial recognition, regardless of race or age. I do not think that throwing out all victim IDs would be beneficial to justice.
I am quite sure now that often, very often, in matters concerning religion and politics a man's reasoning powers are not above the monkey's. -Mark Twain
