This is a terrible idea, eyewitness identifications are already problematic and unreliable, now we want to throw this into the mix? The police were extremely dumb here - if the witness said there were no facial tattoos, why was a person who had them included in the photos in the first place? And if the offender DID have facial tattoos, then perhaps all of the photos should have as well? Cops gonna cop I guess

Oh and gee, I wonder what groups of people would get screwed the most by this
