So a short bald guy, a fat redheaded guy and a tall blond guy walk into a lineup...

This asserts some facts that I hadn't heard before, but if they are true, what are the implications?

"It is our understanding that the investigative practice of 'line-ups' is based upon the people in the line-up exhibiting a reasonable likeness to the description of the person alleged to have committed the crime. It has been widely reported that the 'Black Book,' which was at issue during the end of Chief David Wray’s tenure contained 19 photographs of African American officers who were reportedly on duty during the time that a reported sexual assault occurred. Further, information indicates that officers in the photo line-up had a range in age of at least 20 years, ranged in height from approximately five feet five inches tall to six feet and five inches tall, ranged in weight from approximately 170 pounds to approximately 390 pounds, in skin complexion from very dark-skinned to very light-skinned, and had a combination of full heads of hair to completely shaved heads."
