Reasonable Doubt Part 2: Eyewitness Testimony

Last week, as part of this series on wrongful convictions, I wrote about why it’s so important for average citizens to understand what reasonable doubt is, and how a “not guilty” verdict is not the same as finding a defendant “innocent”. You can read other parts in this series about wrongful convictions in America called Reasonable Doubt. Here are the other parts:

This week, for part two, I want you to watch something. This is the OJ Simpson trial, which involved a lawyer from the Innocence Project. Here was a perfect example of reasonable doubt. You can generally find out what sort of juror you will be by your opinion on this trial. If you would have agreed with the verdict that the jury came to, you probably have a very good understanding of what reasonable doubt means. If you would have found him guilty, then you would likely be an emotional juror and the chances of you serving on a jury that might accidentally put away an innocent man are pretty good.


Watch this:



What you see in this video are two things:


1. This was race-related. The verdict, in this case, was important to the black community because the black community is overwhelmingly and disproportionately blamed for most crime in the USA when stats, studies and facts all show that they do not, and have never, committed near half of the crime in the US. Putting away innocent black people for crimes they did not commit doesn’t just happen often. There is no doubt in my mind, this happens daily.


Consider these facts:

  • 13% of the US population is black.

  • 40%+ of the US prison population is black.

  • African Americans make up the majority of people serving time for nonviolent drug offenses.

  • Black youth are arrested ten times more for drug offenses than white youth.

  • 5 times as many white people report using illicit drugs as black people. Five times.

2. The line toward the end of this video, “One question hangs in the air. If OJ Simpson did not murder his ex-wife and her friend… who did?” illustrates the misconception of the jury system perfectly. OJ was not found innocent, he was found not guilty. There is a vast difference. A not guilty verdict can be made even when jurors feel the defendant did, in fact, commit the crime being examined. The difference is the question, “does the evidence support my opinion beyond a reasonable doubt?”. If the answer is no, a not guilty verdict is necessary, even if it is your opinion that the man committed the crime.  This is the only way we can avoid wrongful convictions in the current justice system.


The causes of wrongful convictions are many, and they include emotional juries. The number one cause, however, is eyewitness testimony.


Neil deGrasse Tyson once said,


Eyewitness testimony is the lowest form of evidence in science. Which is sad, because it’s the highest form of evidence in the court of law.


Tyson was actually called for jury duty on a couple of occasions and was dropped both times as a potential juror. The first time they excused him from serving on a jury, it had been after this conversation:


Lawyer: “I see you’re an astrophysicist. What’s that?”


Tyson: “Astrophysics is the laws of physics, applied to the universe—the Big Bang, black holes, that sort of thing.”


Lawyer: “What do you teach at Princeton?”


Tyson: “I teach a class on the evaluation of evidence and the relative unreliability of eyewitness testimony.”


He was immediately excused. Why? Because the majority of cases in the US rely on eyewitness testimony and with Tyson on the jury, they knew they wouldn’t get a conviction.


Here are a few things to consider about eyewitness testimony:

  1. Eyewitness testimony is what is happening when people insist they have “found God”, witnessed a miracle, had their prayers answered, been abducted by aliens, seen a ghost, el chupacabra, Bigfoot or Nessie.

  2. Continually, studies on eyewitness testimony show that it’s a 50/50 toss up, whether or not the eyewitness is correct.

  3. 72% of all wrongful convictions that have been overturned with DNA testing, were based on false eyewitness testimony.


It’s an unsettling thought, the idea that our memory is only reliable half the time and we really have no idea which half it is. It being unsettling, however, does not make it any less true.

Have you ever been discussing old times with a friend or a family member and gotten into a debate over whose version of events was right? Maybe it’s a Christmas dinner where Grandma burned the potatoes, but your brother is sure it was the brussels sprouts that had been burned. Both of you are perfectly certain of your version, but someone has definitely recalled what happened incorrectly. Maybe even both of you have. This scenario is so common, there’s probably not one of you reading this who has not experienced it.


Our memories are not video cameras that record the events in our lives exactly. They often replace old information with new information, and memories morph over time. For instance, taking the example of Grandma’s brussels sprouts. Maybe your brother is right, she did burn the brussels sprouts, but you recall it being the potatoes because recently at Thanksgiving, someone did burn the potatoes and you told the story of grandma’s burned sprouts at that dinner, and the two became jumbled in your mind.


There are many other ways in which your memory can be jarred into remembering something wrong over something right.


Memory can be drastically affected by stress and strong emotions. If you’re witnessing a crime, chances are, you are experiencing stress and strong emotions. You might be terrified or sad or you might feel overwhelming anger and a desire to have someone pay for the crime. These are powerful emotions that can, when you see a line-up, cause you to find one feature of a man familiar and think, “that’s him! Get him!” without assessing anything else about the men in front of you. At that moment, you begin to associate that man’s face with the crime that has been committed and any time a cop shows you a photo of him, you will pick him out.


Pressure, exhaustion and a desire for this all to just be over can also lead you to identify the wrong person. A small glimmer of hope that the police have brought in the real perpetrator will make you stretch what you recognize just to have this part of the investigation and trial be over and done with.

Suggestions by police can affect your memory as well. If you’ve ever watched a crime drama on TV, you’ve seen a cop slide over a mug shot of a single man and ask, “Is this the man who hurt you?”. This happens all the time in real investigations and is, in itself, suggestive. Sometimes cops will offer you a whole page or booklet of photos, but one photo is different in some way. Maybe he’s the only black man in the set of photos, maybe he’s the only one with a beard as you described the real perpetrator to have, or maybe the police have marked his picture in some way (which they do). This is also leading and happens more than any of us should feel comfortable with.


Our vision can also play tricks on us. Even perfect 20/20 vision deteriorates drastically at a distance or in poor light.


Sometimes, there is no reason that can be pinpointed. Sometimes, our memory just sucks.


Take into consideration the case of Jennifer Thompson-Cannino. In 1984, as she slept alone in her apartment, a man broke in. She was awoken, saw him in her room and began screaming. The man then held a knife to her throat to shut her up and she offered him anything he wanted to leave her alone. Face to face, they spoke. He said he was not interested in money and proceeded to rape her. Horrified, Jennifer refused to let this man get away with what he was doing. She vowed, while she was being attacked, to study this man’s face. Every last mark, scar and expression. She studied his face the entire time she was being attacked and was beyond confident she could identify this man in a court of law. Jennifer was not a drug user. She was a respected and accomplished college student. She was healthy both physically and mentally and she swore she could recall that face like she could her own mother’s.


Able to escape her apartment with her rapist still there, she ran and found police. The perpetrator left and raped another woman nearby.


Jennifer reported her crime and after evidence was collected and a composite sketch of her attacker was made, the police laid out a photo line-up of men, including Ronald Cotton who was identified in a tip that came in that he resembled the sketch. The police, correctly following procedure, told her the man they were questioning may or may not be in the photos.


Jennifer studied the photos carefully and picked Ronald.


When asked if she was sure, she assured the detective that she was indeed.


Ronald was brought in for questioning. He gave a mistaken alibi, having mixed up which weekend was in question. This made the police think he was lying.


Ronald Cotton was put in a physical lineup shortly after, from which he was pointed out by Jennifer (who, as we know, had chosen his photo as well).


She was absolutely sure.


The evidence was presented at trial. A sane, sober woman told the jury that as she was attacked by this man, she studied every feature of his face and had no doubt in her mind that Ronald Cotton was that man. The prosecution then also brought to light that he had “lied” about his alibi for that evening.

Imagine yourself on that jury. Imagine listening to 22 year old, pretty, responsible, ambitious, blond Jennifer tearfully point out Ronald as her attacker and explain in detail the horror of her attack. Imagine what you would feel in that moment. Likely, rage would be building up inside of you. Sympathy for Jennifer would grow. Then you would be told that Ronald made up a story for his alibi, which was proven to be wrong. Ronald appeared to be a liar. Imagine yourself in that situation. It would appear that Ronald was guilty, no? Most people in today’s world, save for Neil deGrasse Tyson and a handful of Innocence Project volunteers, would have found him guilty and you can hardly blame them for that, can you?
