FOUR SECONDS

When a Moment of Violence Is Judged by Those Who Were Never There

by CEJames (researcher/author) & Akira Ichinose (editor/research assistant)

 

A note on what follows: This is a work of narrative nonfiction-style storytelling. The central character, Marcus Webb, is fictional. The science, legal frameworks, psychological research, and institutional dynamics described throughout are real and documented in the bibliography. The story is constructed to carry those realities across to the reader in a way that clinical analysis alone cannot.

 

Part One: The Four Seconds

Marcus Webb did not remember making a decision.

That is the first thing you need to understand — and it is also, somewhat ironically, the thing that will work hardest against him in the months to come. He will be asked, under oath, with a court reporter clicking away and twelve jurors watching his face, to explain what he was thinking. He will be asked to reconstruct his reasoning. He will be asked why he did not simply step back, call out, wait another moment. And he will find himself staring at the table in front of him, because the honest answer — the neurologically accurate, physiologically documented, utterly true answer — is that there was no reasoning to reconstruct. There was threat, and then there was response, and between those two things there was almost nothing that resembled the deliberate human cognition the courtroom expects to hear about.

The evening in question was unremarkable up until it wasn't. Marcus had been walking from his vehicle to the front entrance of a convenience store in the kind of parking lot that exists in ten thousand American cities — bad lighting at the perimeter, a concrete island of gas pumps in the middle, a strip of asphalt connecting everything in a rough rectangle. It was a Tuesday. He had stopped for a bottle of water and, maybe, a bag of pretzels. He had no idea that within two minutes he would be in a fight for his life.

The man who approached him came from his left and slightly behind — what martial artists and military trainers call the seven o'clock position. Marcus did not see him until he was already close, already accelerating, already swinging. The first swing missed. The second did not. Marcus absorbed a strike to the side of his head that produced, as he would later describe it, a sensation like having a television change channels inside his skull — one moment normal reality, the next a buzzing, tilted version of the same scene.

What happened next consumed approximately four seconds. That is not an approximation for dramatic effect. Security camera footage, reviewed frame by frame by an investigator hired by Marcus's attorney, documented the entire physical encounter from the moment of first contact to the moment Marcus's attacker was on the ground. Four seconds. In that interval, Marcus experienced an adrenaline spike that researchers estimate would have flooded his system with a cortisol and epinephrine cocktail sufficient to measurably alter his color perception, his hearing, and his fine motor control. His heart rate would have spiked — research by Alexis Artwohl and Loren Christensen suggests that under extreme threat, the heart can surge past 175 beats per minute in a matter of moments, and at those rates the prefrontal cortex essentially goes offline as the body routes its resources to faster, older, survival-oriented brain structures.

He threw three strikes. He used what he had trained — Isshin-ryu karate, the Okinawan system, years of kata and kumite and the particular understanding, drilled in the dojo until it was reflex, that in a real altercation you protect the centerline and you do not stop until the threat stops. The attacker went to the ground. Marcus stepped back. He scanned the area for secondary threats — another trained response, automatic as breathing. Then he called 911.

Four seconds of violence. He was home by eleven that night.

The legal process that followed lasted nineteen months.

 

Part Two: The Room Where Time Slows Down

Courtrooms have a relationship with time that is fundamentally alien to the events they are asked to judge.

This is not a criticism of courtrooms, exactly — it is simply a description of what they are. A courtroom is an institution designed to ensure that consequential decisions are made carefully, with full consideration of all evidence, with the opportunity to challenge and cross-examine and deliberate. These are genuinely good things. The courtroom's slow pace is a feature, not a bug. It exists precisely because the consequences of getting it wrong — a wrongful conviction, a wrongful acquittal — are serious enough that the system has decided to err on the side of thoroughness.

The problem is that thoroughness and violence operate on incompatible timescales.

By the time Marcus sat at a defense table, the four seconds in that parking lot had been expanded, analyzed, and dissected across tens of thousands of words of testimony, report, and argument. The prosecution's use-of-force expert had prepared a 47-page written analysis. A biomechanical specialist had reviewed the security footage and produced diagrams showing the angle of Marcus's strikes, the positioning of his feet, the degree of force applied as estimated from the attacker's movement on impact. A psychologist had written a 22-page report on Marcus's background, his training history, and what his training history might imply about his state of mind. Medical records from the emergency room documented the attacker's injuries in clinical granularity.

Four seconds had become 200 pages.

Each of those pages was produced by someone who had not been there. Not a single expert, not a single attorney, not a single juror had stood in that parking lot at that moment with a man's fist connecting to the side of their skull, their inner ear ringing, their visual field narrowing as the survival brain took over. Every analysis, every diagram, every carefully worded conclusion had been produced in an air-conditioned office, at a desk, with a cup of coffee nearby, with all the time in the world, with the ability to pause and rewind the footage and zoom in and zoom out and go home for dinner and come back the next morning and look at it again.

This is the fundamental epistemological chasm that sits at the heart of every self-defense case ever tried, and it almost never gets named directly.

 

Part Three: The Standard and the Gap

American law — and most Western legal systems — evaluates self-defense claims using some variant of what is called the reasonable person standard. The question, in its simplest form, is whether a reasonable person in the defendant's situation would have believed that the force used was necessary to prevent serious bodily harm or death. This is sometimes called an objective-subjective hybrid: subjective in the sense that the jury is supposed to consider the situation from the defendant's perspective, as they perceived it in the moment; objective in the sense that the defendant's perception is then measured against what a hypothetical reasonable person would have perceived.

The legal scholars who developed this standard were not stupid. They understood that you cannot judge a person's actions in extremis using purely external metrics that ignore their inner experience. That is why the standard says 'in the defendant's situation' rather than simply 'given the facts.' The law is trying to do something genuinely difficult — honor the subjectivity of the actor while still applying a normative check against which individual claims can be measured.

But the gap between the legal aspiration and the courtroom reality is wide enough to drive a truck through.

Research by David Klinger, published in his book Into the Kill Zone, and by Karl Weick on sensemaking under uncertainty, converges on the same essential point: what a person perceives, understands, and decides in the midst of violence is shaped by factors — stress physiology, prior training, threat-environment conditions, available attentional resources — that cannot be adequately communicated in retrospective verbal testimony. When Marcus takes the stand and says 'I thought he was going to kill me,' he is producing a post-hoc verbal translation of something that was never, in the moment, a verbal thought at all. The belief was embodied. It lived in his muscle memory and his autonomic nervous system and his threat-assessment hardware. Turning it into a declarative sentence for the benefit of twelve people in comfortable chairs introduces layers of distortion that neither Marcus nor his attorney can fully undo.

And then there is the expert.

 

Part Four: The Expert Who Was Also Not There

The prosecution's use-of-force expert — a retired law enforcement officer with eighteen years on the job and a consulting practice — is a genuinely knowledgeable man. He has studied force encounters. He has reviewed hundreds of cases. He has testified in dozens of trials. He knows the literature on police use of force better than most. He is, by any reasonable professional standard, an expert.

He also watched the parking lot security footage approximately sixty times in slow motion on a 27-inch monitor before forming his opinion that Marcus had used excessive force.

This is the paradox of the use-of-force expert in a self-defense trial, and it is a paradox that criminologist Geoffrey Alpert and researcher William Smith have written about at length: the expert's analysis is, almost by structural necessity, shaped by a mode of perception that is the precise opposite of what the defendant experienced. The expert sees the footage slowly. He sees all of it. He sees what happened after the first strike, knows what the attacker did next, can evaluate Marcus's third strike with full knowledge of what the second accomplished. He has no noise, no adrenaline, no blood in his eyes, no ringing in his skull. He has a chair and a screen and a mouse and a pause button. From this position of radical informational and physiological calm, he concludes that Marcus was unreasonably aggressive.

There is a name in the research literature for the cognitive trap the expert has fallen into, even if he doesn't know it. Psychologist Neal Feigenson, writing in the Connecticut Law Review, calls it the hindsight bias of the reconstructed sequence: because the reviewer knows the outcome — knows the attacker went down, knows he did not die, knows Marcus was not further injured — the reviewer's assessment of threat is retrospectively calibrated toward that outcome. The attacker turned out not to be lethal; therefore, the reasoning goes, the level of force applied was disproportionate. The problem, of course, is that Marcus did not know the attacker would turn out not to be lethal. He could not know that. No one can know that in four seconds.

What Marcus knew, in the way that a person can know things in the body rather than the mind, was that he had been hit hard enough to disorient him, that the man was still moving toward him, and that he needed to stop the threat. This is exactly what he did. And now he is sitting in a courtroom while a man who was sixty miles away at the time tells twelve strangers that what he did was wrong.

 

Part Five: The Twelve

The jurors are not bad people. This is important to establish before saying anything else about them, because what follows might otherwise read as an indictment of the institution of the jury itself. It isn't. The jury is, for all its imperfections, a genuinely important safeguard. Twelve people who represent the community sitting in judgment of community behavior is a fine idea. It is, in its origins and in its best functioning, a protection against state overreach that has demonstrably mattered throughout history.

But the jurors are operating under constraints that research has documented in some detail, and those constraints bear on Marcus's case.

The first is what psychologists call the just-world hypothesis — a cognitive tendency, identified by Melvin Lerner in his landmark 1980 study, toward the belief that people get what they deserve. Jurors who hold a strong just-world orientation tend to scrutinize victims more harshly when the victim appears to have behaved in ways that might have contributed to their situation. The man Marcus struck was, by the time the case reached trial, a victim in the legal sense. His injuries were documented and presented to the jury. His medical bills were referenced. His pain was verbally described. This is appropriate — the state is required to establish the harm caused. But it also has the effect of activating just-world thinking, which can lead jurors to ask whether Marcus did more than was strictly necessary, rather than whether he did what a reasonable person would have done under extreme threat.

The second constraint is the availability heuristic — the tendency, documented by Kahneman and Tversky in their foundational work on cognitive bias, for people to assess the likelihood of events based on how easily examples come to mind. For most jurors, actual violent physical confrontations are not part of their lived experience. What they know about violence, they know from movies, television, and news. In media portrayals, violence has a rhythm and a clarity that real violence does not. Heroes land clean strikes and step back. Villains absorb punishment in a way that makes the outcome readable. There are moments of hesitation and decision that the audience can track. Real violence doesn't work this way — it is chaotic, ugly, and fast in ways that no juror, sitting in a box hearing testimony about it, is truly equipped to viscerally understand.

The third constraint is perhaps the most troubling: the retrospective construction of a decision-making process that never existed. When jurors are asked whether Marcus had time to de-escalate, whether he could have retreated, whether his third strike was necessary, they are being asked to reason about a mind that was not, in the relevant sense, engaged in reasoning at that moment. They are being asked to audit a non-existent deliberation. 

The question 'why did you decide to throw that third strike?' presupposes that there was a decision, in the slow deliberate sense the question implies. There wasn't. There was training and threat and time moving faster than thought.

 

Part Six: The Tachypsychia and the Transcript

Tachypsychia is one of those words that takes a complex reality and makes it accessible by naming it. From the Greek tachys (swift) and psyche (mind or soul), it refers to the perceptual time distortion that occurs under extreme stress — the phenomenon in which time seems to slow, speed up, or fragment, and in which sensory information is processed in ways dramatically different from normal waking consciousness.

It is well-documented. Artwohl and Christensen, in Deadly Force Encounters, surveyed hundreds of officers who had been involved in shootings and found that significant percentages reported tunnel vision, auditory exclusion (gunshots that they did not hear), and the sensation that events were unfolding in slow motion. Other research has documented intrusive visual memory — vivid, unbidden recall of specific details — alongside near-complete gaps in other aspects of the event. A person can remember with extraordinary clarity the pattern on the attacker's shirt and have no memory of exactly when or why they threw a particular strike.

This creates an obvious and profound problem for a legal system built on the assumption that a defendant can provide coherent, sequential, internally consistent testimony about what they did and why.

When Marcus testifies, he does the best he can. He describes the initial strike. He describes the disorientation. He describes, in general terms, the sense of continuing threat. But he cannot provide the kind of blow-by-blow account with clean causal chains that the prosecutor's cross-examination demands, because that kind of account is literally neurologically unavailable to him. His hippocampus was not taking reliable sequential notes. His prefrontal cortex was largely offline. The parts of his brain that were running the show during those four seconds are parts that do not communicate in the language of courtroom testimony.

The prosecutor will later tell the jury, in closing argument, that Marcus's inability to provide a clear account of his reasoning 'should raise questions.' And perhaps, to a jury that doesn't know about tachypsychia, it does.

 

Part Seven: What Training Means and What It Costs You

There is a particular cruelty in the way that training — which is supposed to make you better at surviving violence — can be weaponized against you in the legal aftermath of surviving violence.

Marcus trained. He has trained for years. He holds rank in Isshin-ryu, a practical, body-driven Okinawan system developed by Tatsuo Shimabuku and built around the biomechanics of real confrontation — upright stances, short punches, close-range knee strikes. He attended class regularly. He received instruction that included not just technique but the philosophy of the art: Isshin-ryu means one heart way, a name that speaks to the integration of mind and body, to technique that has been internalized so deeply it is no longer a set of moves but a way of moving. He trained because he believed — reasonably, correctly — that if violence ever came for him, preparation was better than the alternative.

In the courtroom, this becomes evidence of something sinister.

The prosecutor will argue that Marcus's training made him more dangerous, that his response was not the response of an ordinary person but the response of someone with specialized knowledge of how to hurt people. This argument has a surface plausibility that is nonetheless deeply misleading. Training doesn't make a person more aggressive — it makes a person more efficient. More to the point, it makes a person more capable of calibrating response to threat rather than less, because an untrained person panicking under a violent assault is far more likely to produce catastrophic results than a trained person drawing on years of deliberate practice. But this requires a nuanced understanding of how training works that a courtroom is not always equipped to evaluate.

The deeper point is this: we tell people to prepare. We tell them that self-reliance is a virtue. We teach situational awareness and de-escalation and the responsible carrying of defensive tools. We build entire curricula around the idea that citizens who are prepared for violence will produce better outcomes than citizens who are not. And then, when a citizen who prepared for violence uses that preparation to survive it, we put him in a courtroom and use his preparation as evidence of premeditation.

There is something genuinely incoherent here. Marcus Webb trained so that if someone attacked him, he would survive. Someone attacked him. He survived. Now twelve people who were not there are being asked to decide whether he survived in the right way.

 

Part Eight: The Verdict and What It Leaves

Marcus was acquitted. This matters, and it would be dishonest to write around it — he was acquitted, which means the system, in the end, worked as it was supposed to work. The jury, after three days of deliberation, returned a not guilty verdict on the charge of aggravated assault. The forewoman, speaking to a local news outlet afterward, said that the jury had struggled but that ultimately they believed Marcus had acted out of genuine fear for his life.

So the story has a good ending. Except.

Except that nineteen months is a long time to live under a felony charge. Except that Marcus's legal defense cost roughly $47,000 out of pocket — a number that would have been financially catastrophic for many people, and was merely very hard for him. 

• Except that his employer, a private logistics company, placed him on administrative leave during the trial, which he survived only because he had savings. 
• Except that his marriage, already under the stress that comes with working the hours he worked, did not survive the nineteen months that followed. 
• Except that the attacker, who had a documented history of violent assault and was himself on parole at the time of the incident, was never charged with anything.
• Except that Marcus, when he talks about it now, says that the hardest moment of the entire ordeal was not the four seconds in the parking lot. 

It was sitting in a conference room with his attorney, watching the security footage played back on a laptop, watching those four seconds expand into ten minutes of frame-by-frame analysis, watching a diagram showing his strike angles appear on a legal pad, and realizing, with a clarity that hit him like the blow that started everything, that the experience of being attacked and defending his life had been converted into a set of data points to be argued about by people who would never understand what it felt like from the inside.

'It was like being told,' he said, 'that the language I spoke didn't count.'

 

Conclusion: The Unbridgeable Gap and What We Owe Each Other

This essay is not an argument that self-defense claims should never be scrutinized. Of course they should. The legal system's obligation to examine force used against another human being is not a bureaucratic inconvenience — it is a moral necessity. 

• People lie about self-defense. 
• People use the claim retroactively to cover aggression that was not defensive at all. 

The courtroom's slow, careful, adversarial process exists because the stakes are high enough to warrant that care.

But there is a category error built into that process when it is applied to the specific neurological and physiological reality of genuine violent confrontation, and that category error costs real people in real and serious ways. The error is the assumption that because a court can reconstruct events after the fact, the person who lived those events was operating with equivalent information and time during them. The error is treating four seconds of survival as if it were a considered policy decision that could have been made better.

What the research suggests — from Grossman's work on the physiology of killing, from Artwohl's surveys of stress responses in lethal force encounters, from Kahneman's decades of work on the limits of human cognition under pressure — is that the honest answer to 'what were you thinking?' in the midst of extreme violent threat is almost always 'I wasn't thinking, in the way you mean. I was surviving.'That answer deserves to be treated as the scientifically grounded truth that it is, not as an admission of irrationality or a failure to account for one's actions.

We ask a great deal of people who are forced to defend themselves. We ask them to respond correctly, efficiently, and proportionately to a situation no human nervous system is really built to evaluate in real time. And then we ask them to sit in a room for nineteen months and explain their response to people who have had nineteen months, all the relevant footage, 200 pages of expert analysis, and a comfortable chair.

The least we can do is be honest about what those two situations have in common, and what they don't.
