Honest But Inaccurate: Why Video Doesn’t Capture What Is Experienced

Originally published on the Force Science Institute website. Republished here with permission.

In 2013, Force Science News shared the story of a Grover Beach (CA) police officer who was fired after attempting to use his TASER® device on a kidnapping suspect. After forcing entry into a garage, officers found the man sitting in a car with the baby in his arms. With only the light from his TASER device to illuminate the “pitch black” garage, one officer watched and listened as the baby had to be “forcefully pulled away” from the suspect. The officer later described the suspect as noncompliant, “using his size and arm muscles” to resist arrest.

To quickly end the “struggle,” and without warning, the officer fired his TASER device at the suspect’s back. Although nobody was hurt during the arrest (the device failed to shock the suspect), there was still a problem. The video captured by the TASER device camera did not show any resistance by the suspect—not when the baby was taken from his arms and not during the final arrest. Believing the officer had lied to justify his excessive force, the city, with the chief’s support, fired the officer.

Readers familiar with the case may recall that the officer was ultimately reinstated, but not before three years of back and forth administrative hearings and litigation. The question facing the Grover Beach agency, community, and court was whether inconsistencies between an officer’s report and video evidence necessarily means that the officer is lying. As the court concluded, it does not.

Explaining the Differences

It is undoubtedly true that one reason an officer’s report might be inconsistent with video evidence is that the officer has made the conscious decision to lie. But the question remains whether there are other, less sinister explanations for these inconsistencies. As it turns out, there are plenty.

In a 2016 Lexipol training program titled “Point/Counterpoint: The Debate over Officer Viewing of BWC Video Footage,” Ken Wallentine, senior attorney and graduate of the Advanced Force Science Specialist program, noted: “Cameras don’t track with an officer’s eyes. They don’t capture tactile cues, such as when a suspect flexes muscles and starts to resist. They don’t reveal a suspect’s prior history known to the officer. They don’t record at the speed of life. They don’t capture images in 3-D or represent distances accurately. They don’t accurately reproduce what the human eye sees, and they don’t reproduce the subjective fear an officer feels.”

Trying to distinguish lies from “honest but not accurate” police reporting is an issue that continues to incite controversy and division across the country today.

It seems the judge in the 2010 Grover Beach case made similar observations when she rejected the allegations that the officer made intentionally false or misleading statements: “While in hindsight, and with a calm viewing of a videotape that does not record at the same rate and perception of a human eye, it may appear that the struggle was not as serious as the officer described,” the judge wrote. However, she continued: “There clearly, based on the testimony, was more happening at the scene than is viewing on the video and the Court cannot say that the use of the Taser, in this situation, was unreasonable.”

The idea that there could be “more happening at the scene” than what an officer might remember is supported by Dr. Bill Lewinski, executive director of the Force Science Institute. “It is the focus of attention and not the operation of the senses that determines what information is perceived. No matter what is occurring at the scene or captured on the video, if something is not perceived, it cannot be remembered.” He continues: “Once our attention is focused on an object, or even a thought, we have a limited capacity to attend to other tasks or stimulus. The resulting attentional tunneling and attentional blindness have been well-researched for decades. These concepts are not usually considered controversial until law enforcement officers fail to report every detail that occurs at a scene.”

The Nature of Inaccuracy

Research continues to provide reasonable explanations for memory gaps and perception distortions. Still, trying to distinguish lies from “honest but not accurate” police reporting is an issue that continues to incite controversy and division across the country today.

More than any other time in our history, police leadership and politicians feel immense pressure to restore confidence in communities convinced American police are not to be trusted. In response, officers are losing their jobs and, in some cases, being prosecuted simply because their version of events is “contradicted by doesn’t align exactly with video evidence.

But what if these contradictions are not actually evidence of intentional deception and instead reflect the predictable outcome of comparing imperfect video against imperfect humans? How do we prevent agencies, courts, and communities from presuming that “inaccurate” or “incomplete” must mean “untruthful”?

Perhaps we start by attempting to understand the meaning of untruthfulness.

How do we prevent agencies, courts, and communities from presuming that “inaccurate” or “incomplete” must mean “untruthful”?

Honest Belief

At the most fundamental level, it’s expected that for something to be “true,” what we believe or say must correspond to the way things actually are. This is the concept of coherence. “Untruthful” then is the character of a belief or statement that is merely inconsistent (incoherent) with objective facts.

Now compare “untruthful” with “deceptive.” Deception requires a person to believe or think one thing and consciously express another. “Honest belief” then is what distinguishes “untruthful” from “deceptive.” It leaves room for the inconsistencies that can result from human performance factors—including attention, memory and perspective.

Honest Accountability

It’s critical that agencies distinguish between inaccurate (but nonetheless honest) beliefs and deception. In some cases, even the allegation that an officer was “untruthful” can trigger a required disclosure under Brady and effectively destroy the officer’s perceived credibility and challenge the profession’s legitimacy.

Dishonest officers should be culled from the profession. But unfairly labeling an officer as dishonest based on the inconsistencies that can result from known, and often unpreventable, human performance factors is itself dishonest and unethical.

Communities are demanding police transparency and accountability. To instead offer them an overly simplistic view of human performance and sacrifice the complexity, nuance, and reality of policing—this is patronizing to the community and immoral to the officers.
