0:00 In seventy-six percent of wrongful convictions overturned by DNA evidence, the deciding factor was an eyewitness.0:09 Last week, we sat with the weight of bearing witness to injustice.0:15 Today, we look at what happens when the witness...0:19 is the one who gets it wrong.0:22 They sat him in the courtroom when he was seventeen years old.0:27 His name was Marvin Haynes.0:30 The charge was murder.0:32 There was no DNA, no weapon, no physical evidence tying him to the crime.0:38 There was only one thing… an eyewitness.0:42 And she was certain.0:43 You could feel the weight of her certainty in the room.0:48 Jurors lean in for that.0:50 A person, looking another person in the eye, and saying: that’s him.0:56 That’s the man I saw.0:58 And so for nearly twenty years, that was the story.1:02 A confident witness, a quick conviction.1:06 But memory isn't a recording.1:08 It isn't a video you can just rewind and play back with perfect clarity.1:15 It’s a reconstruction.1:17 It’s a story the brain tells itself, and it’s a story that can be edited.1:23 By stress.1:24 By trauma.1:25 By the simple, terrible fact that it’s harder to identify someone of a different race.1:32 And most of all… it can be edited by the people asking the questions.1:38 We want to believe what we see.1:41 And in that courtroom, everyone believed what she said she saw.1:46 Marvin Haynes was sentenced to life in prison.1:51 But someone, somewhere, kept pulling at the thread.1:55 Someone from the Great North Innocence Project sat with the court records, year after year, with that quiet, persistent feeling that the story didn't fit.2:08 And they started asking different questions.2:12 Not "what did the witness see," but "how was she asked to see it?" And that’s where the whole thing… unraveled.2:22 The police lineup.2:23 It wasn't blind.2:25 The officer who showed her the photos knew exactly which one was Marvin.2:31 And when she hesitated, when she wasn't sure… there was feedback.2:37 A subtle suggestion.2:39 Her memory wasn’t being tested.2:41 It was being FORMED.2:43 The psychologist Karen Newirth explained it perfectly.2:48 Once a name or an image is introduced, especially in a suggestive way, the brain can latch onto it.2:56 It overwrites the original, fuzzy memory with this new, confident one.3:03 The witness wasn't lying.3:05 That's the tragedy.3:06 She was absolutely sure of a memory that was never really hers to begin with.3:13 After almost two decades, Marvin Haynes walked free.3:18 But the cost is staggering.3:20 Not just for him, but for the victim’s family, who never got justice because the real perpetrator was never caught.3:30 The system is slowly, finally, admitting this is a problem.3:35 Courts in New York are now demanding expert testimony on how memory works, demanding that juries be told about the fallibility of eyewitnesses.3:48 We are learning, at a terrible price, that the most convincing evidence in a courtroom is often the most dangerously unreliable.3:59 The truth isn’t what you see; it’s what you can prove.
