Think of how it must be for the 4 people on the stand who answered yes. They were likely shown a few pictures along with the implication that they were "usual suspects", one of which was almost certainly the culprit. They'd probably seen all of about 5 real-life "people of color" in their lives and simply picked the closest looking one to what they remembered. The system then automatically worked to assure them that this was the guy. Over time their memories sloshed together with the picture and the guy on the bench and then they were sure of it. But now they know that they were 100% wrong and their testimony cost this guy his life. That's a tough one to live with.
