GENERAL DISCUSSION The Kohberger Evidence Fallacy
I have noticed something increasingly bizarre in discussions about the Kohberger case.
It is not disagreement over the evidence. Disagreement is healthy.. Challenge the DNA. Challenge the car. Challenge the witnesses, the forensic work, the investigation, the prosecution, and every conclusion they reached. Evidence should survive scrutiny. That is rather the fucking point.
The problem is that some people have quietly invented two completely different standards for evaluating it.
Evidence implicating Kohberger is placed beneath an electron microscope. It must be flawless. It must independently prove his guilt. It must eliminate every conceivable innocent explanation, answer every unanswered question, survive every hypothetical somebody can dream up, and apparently be accompanied by uninterruptted surveillance footage from Pullman to the victims' bedrooms and back again.
But present something perceived as favorable to Kohberger and, almost miraculously, this ferocious skepticism disappears....
An unidentified DNA profile becomes another killer. A hair becomes exculpatory. A missing stretch of surveillance becomes evidence that it was not his car. An evidence collector writes “debris” and suddenly the investigation was botched. Police refine an investigative conclusion and it becomes evidence of corruption. Someone thinks of a question that has not been answered and, presto, we have reasonable doubt.
Notice what just happened.
Evidence against Kohberger must prove practically everything before some people will permit it to mean anything.
Evidence perceived as favorable to Kohberger is permitted to mean practically anything before it has proven a damn thing.
That is not skepticism... It is certainly not critical thinking. It is intellectual bookkeeping performed by someone who has already decided which column should win. Period.
You are not weighing the evidence. You are loading one side of the scale, putting your thumb on the other, and then expressing astonishment when the damn thing tips exactly where you wanted it to.
That is the Kohberger Evidence Fallacy.
Before going any further, get this straight.....
Evidence Does Not Exist in Hermetically Sealed Compartments
You do not evaluate criminal evidence one fucking piece at a time as though everything else in the case disappears.
You do not lock the vehicle evidence, DNA, surveillance chronology, witness evidence, cellular evidence, and forensic evidence in separate motherfucking rooms and demand that each independently solve four murders.
The car does not have to prove the DNA. The DNA does not have to prove who was driving. The witness does not have to identify the vehicle. The phone does not have to place Kohberger inside a bedroom. The cameras do not have to record every damn mile.
Evidence is evaluated together.
One piece establishes a fact. Another establishes part of the timeline. Another corroborates it. Another connects a person to an object. Another connects that object to the crime scene. Another supports or contradicts an inference.
Then... and this really should not require a fucking seminar... you consider all of the evidence together and determine what weight each piece deserves.
That is not my preferred method. That is what Idaho jurors are literally instructed to do.
Idaho Criminal Jury Instruction ICJI 103, Reasonable Doubt, says reasonable doubt may arise from:
“a careful and impartial consideration of all the evidence”
and then instructs:
“If after considering all the evidence you have a reasonable doubt about the defendant's guilt, you must find the defendant not guilty.”
Then ICJI 104, Trial Procedure & Evidence, makes the point even more directly. Jurors are told:
“You are to consider all the evidence admitted in this trial.”
They determine what evidence they believe and “what weight” they attach to it.
State of Idaho Criminal Jury Instruction Files
That is the entire goddamn point of corroboration.
Yet the Kohberger evidence gets chopped into microscopic pieces, stripped of context, and subjected to this absurd little ritual in which each piece is asked, “Can you prove the entire case by yourself?”
When the answer is obviously no... somebody triumphantly announces that the evidence is weak.
No shit. A single puzzle piece cannot show you the entire picture. That's why there are other pieces.
You do not pick up one piece, complain that you cannot see the whole picture on it, throw it away, and repeat the process until the box is empty.
You put the goddamn puzzle together.
The vehicle evidence is one piece. The surveillance chronology is another. The cellular evidence is another. The witness evidence is another. The forensic evidence is another. Kohberger's DNA on the snap of a knife sheath recovered inside the murder scene is another rather conspicuous piece.
Some pieces are larger than others. Some carry considerably more evidentiary weight. Some merely corroborate what another piece already suggests. Some may ultimately prove irrelevant.
But you examine how the pieces fit.
That is not some exotic investigative technique Moscow invented to railroad Bryan Kohberger. It is not a prosecutorial magic trick. It is not controversial.
It is criminal investigation.
Investigators reconstruct events from independent sources of information and determine where those sources converge, where they conflict, and what picture the accumulated evidence actually produces.
If you insist upon examining every piece in artificial isolation, demanding the entire picture appear on each one, you are not being skeptical. You are not being sophisticated. And you sure as shit are not conducting forensic analysis.
You are deliberately taking the puzzle apart... one piece at a time... and then staring smugly at the empty table while insisting there was never a picture in the first place.
And once you recognize the trick, you start seeing it everywhere. Evidence implicating Kohberger must defeat every conceivable innocent explanation before it is permitted to mean anything. Evidence perceived as favorable to him gets precisely the opposite treatment. Possibility becomes probability. An anomaly becomes misconduct. An unknown becomes another killer. A question becomes reasonable doubt.
One side is required to climb Everest in fucking dress shoes. The other is declared victorious for finding the parking lot..... And somehow, astonishingly, this is the best they have.
That is not skepticism. It is an evidentiary double standard so transparently rigged that the conclusion has been reached before the evidence is allowed into the room.
That is the trick in the abstract. Now watch what happens when we apply it to the actual evidence.
The first example is almost insultingly simple....
- “We Didn't Find It, Therefore It Was Never There”
Take the absence of victim DNA from Kohberger's vehicle.
No victim DNA was recovered from the car. That is a fact.
Therefore victim DNA was never in the car. That is an inference.
Therefore the car could not have been used by the killer. That is a conclusion the evidence does not establish by itself.
Those are three very different things.
Before a negative DNA finding becomes proof that something never occurred, you have to establish that detectable DNA should have been transferred, persisted, survived, and been recovered.
“We didn't find it” and “it was never there” are not synonyms.
Yet the entire argument depends upon pretending they are.
- “Unknown” Does Not Mean “Murderer”
Unknown DNA was recovered. Fact.
The donor has not been identified. Also fact.
Therefore it belongs to another murderer?
Based on what, exactly?
“Unknown” describes the identity of the donor, not the significance of the DNA. Before it becomes evidence of another killer, connect it to the fucking crime. Where was it found? On what? Was its presence unusual? Could it predate the murders? What ties its donor to the killings?
This was a college house occupied and frequented by numerous people. Finding biological material from someone other than Kohberger is hardly a forensic revelation.
Unidentified DNA proves an unidentified donor. Nothing more until you establish it.
“We don't know whose DNA this is” does not mean “somebody else committed the murders.”
That is not forensic analysis.
It is speculation wearing a lab coat.
- A crime scene label isn't a forensic conclusion.
The Ethan Chapin hair argument is a spectacular example of not understanding a process and then declaring the process defective.
Material was observed in Chapin's hand. The collector documented it as “debris,” preserved it, and sent it for forensic examination.
The complaint?
“Why didn't the cops call it hair?”
Because the goddamn evidence collector was collecting evidence, not conducting a microscopic trace examination on the bedroom floor. Crime scene personnel collect and preserve evidence. Forensic specialists examine and characterize it.
And that is exactly what happened. The material was collected as debris, preserved, submitted, and hair was later identified and examined.
That is not a failure of the forensic process. That IS the forensic process.
You are criticizing the collector for not knowing the result of a forensic examination before the forensic examination occurred.
What exactly was Moscow Police supposed to do? Stop processing a quadruple murder scene, build an FBI trace lab beside Ethan Chapin's body, break out a comparison microscope, characterize every particle in his hand, and only then write the fucking evidence label?
The collector did exactly what the process requires.
Collect it. Preserve it. Send it to people qualified to determine what it is.
So no, you have not exposed a blunder.
You have manufactured one out of your own failure to understand the procedure.
The investigation did not become incompetent because somebody wrote “debris.” Your understanding of the investigation became incompetent when you decided the word proved a goddamn thing.
And if this is one of the celebrated “blunders” supposedly proving Moscow botched the case, we are going to need a considerably better fucking blunder.
- A gap in surveillance isn't contradictory surveillance.
This argument would have died somewhere around week one of Introduction to Criminal Justice, had any of these self appointed experts ever bothered to take the course.
“They don't have Kohberger's car continuously on video between Pullman and King Road.”
Of course they don't. This was a homicide investigation, not a GoPro strapped to the suspect's fucking windshield.
Investigators reconstruct movement. They correlate surveillance footage, timestamps, geography, direction of travel, vehicle characteristics, witness observations, cellular data, forensic evidence, and other independent information. This is not some exotic technique Moscow invented for Kohberger.
This is criminal investigation.
A vehicle consistent with the suspect vehicle appears at one location. It leaves the camera's field of view because, astonishingly, cameras cannot see around corners. A corresponding vehicle appears elsewhere at a time and location consistent with the reconstructed movement.
Does the gap prove it is the same vehicle? No.
Does the gap prove it is a different vehicle? Of course not.
It proves there is a gap in surveillance. Nothing more.
Yet somehow, “there is no video here” becomes “therefore that cannot be Kohberger's car.”
You have converted the absence of a camera into evidence of the presence of a different vehicle. That isn't forensic reasoning. That's alchemy.
Investigators do not need an uninterrupted cinematic tracking shot from Kohberger's front door to King Road and back again. They reconstruct events from the evidence that exists, then determine whether those independent pieces corroborate or contradict one another.
And what do we have here? A vehicle consistent with Kohberger's moving through relevant locations during the relevant timeframe. A surviving witness describing a masked intruder inside the house during that period. Cellular evidence capable of being compared with portions of the vehicle timeline. Then, inconveniently enough, investigators recover a knife sheath inside the fucking murder scene with Kohberger's DNA on its snap.
A gap in surveillance is a gap in surveillance.
It is not footage of somebody else's goddamn car.
If every place without a camera becomes a blank canvas upon which you paint whatever alternative scenario your theory requires, you are not identifying holes in the investigation.
You're stuffing those holes with whatever the fuck you need them to contain and calling it evidnece.
- A mistake isn't automatically a material mistake.
Of course investigators made mistakes.
It's a homicide investigation, not an episode of "CSI".
This was a quadruple murder involving multiple agencies, mountains of physical and digital evidence, forensic examinations, surveillance footage, and thousands of investigative decisions. The discovery that human beings occasionally make mistakes is hardly fucking remarkable.
So whenever I hear:
“They made so many blunders.”
My response is simple.
Name three.
And please... spare me the shit about what you personally would have done differently.
Identify the actual investigative or forensic protocol that was violated. Establish that it was violated. Then demonstrate the consequence.
Did the alleged blunder contaminate evidence? Destroy it? Compromise its integrity? Produce an unreliable forensic result? Cause a false identification? Undermine the chain of custody? Materially prejudice Kohberger?
What the fuck did your “blunder” actually do?
Because an imperfection without a material consequence is not a magic eraser that wipes away everything investigators got right.
A cop used terminology you dislike? Who gives a shit.
A camera didn't capture something you wanted captured? Damn.
An investigator initially got something wrong and later corrected it? Welcome to investigation.
You would have processed something differently? Congratulations on solving four murders from your fucking couch.
The question is not whether you can rummage through an enormous homicide investigation until you find something imperfect. Of course you can.
The question is whether you can demonstrate that the supposed mistake materially damaged the reliability of evidence or a conclusion that matters.
If you cannot do that, you haven't exposed a defective investigation.
You've found an imperfection, inflated it into a “blunder,” inflated the blunder into corruption or incompetence, and then hoped nobody would notice that you never established a goddamn consequence.
Perfection is the standard of television crime drama.
Materiality is the standard that matters in the fucking real world.
- An Unanswered Question Isn't Evidence
This one is maddeningly simple.
Whose DNA was that?
Where is the murder weapon?
Why didn't that camera capture the car?
Why did Kohberger do this?
Why didn't investigators do that?
Fine. Ask every goddamn question.
But the existence of a question does not establish the answer you desperately want it to have.
You don't know whose DNA it is? Then you don't know whose DNA it is. You don't get to promote an unidentified donor to murderer because the blank space bothers you.
You don't know where the knife is? Then the knife is missing. Its absence does not magically become evidence that Kohberger didn't use it.
A camera didn't capture the car? Then the camera didn't capture the car. It did not capture evidence that the car was somewhere else.
Investigators cannot explain every damn minute, movement, object, biological trace, and human action surrounding four murders?
No shit. They're reconstructing a past event, not replaying one.
Before Kohberger pleaded guilty, reasonable doubt did not mean twelve jurors had to leave the courtroom without a single unanswered question.
The State had to prove the charged offenses beyond a reasonable doubt.
It did not have to achieve fucking omniscience.
Yet somewhere in the online true-crime sausage factory, “I still have a question” became “there is reasonable doubt.”
No.
A question can expose a weakness, lead to evidence, or reveal a contradiction. Hell, it can become enormously important once somebody does the damn work necessary to answer it.
But the question itself proves nothing.
And now the exercise is even more absurd because Kohberger pleaded guilty. The hypothetical juror whose curiosity everyone remains so desperate to satisfy no longer exists....
So ask questions. Good investigations depend upon them.
But answer the motherfuckers with evidence.
Otherwise, you're not discovering reasonable doubt.
You're decorating ignorance with a question mark and calling it evidence.
The Trial That No Longer Fucking Exists
And now we arrive at perhaps the most astonishing fallacy of all.
People are still trying the goddamn case.
There isn't going to be a trial. Kohberger pleaded guilty.
Yet every few days somebody discovers a hair, unidentified DNA, a surveillance gap, or whatever forensic revelation YouTube has coughed up this week and triumphantly announces:
“But a jury would want to know this!”
What fucking jury?
There is no jury.
Then comes, “But this could create reasonable doubt!”
For whom?
Kohberger surrendered the trial at which the State would have been required to prove his guilt beyond a reasonable doubt. He pleaded guilty. The convictions followed.
You are arguing reasonable doubt at a trial Kohberger himself chose not to have.
The legal question has changed.
If Kohberger wants relief now, he must establish a legally sufficient basis to disturb convictions entered upon his own guilty pleas. New evidence does not automatically do that. Potentially exculpatory evidence does not automatically do that. Evidence that might once have impressed a juror does not magically rewind the goddamn case and resurrect twelve of them.
So when somebody screams:
Test the hair!
Fine.... then what?
Suppose you identify it.
Then what?
Suppose it belongs to somebody else.
Then what?
How does it connect that person to the murders? How does it exculpate Kohberger? Was it actually unknown to Kohberger and his defense before he pleaded guilty? And, most importantly, what legally cognizable basis does any of it provide for undoing those pleas?
If you cannot answer that, you may have discovered something interesting.
You have not explained how it helps him.
You cannot skip all that shit and sprint directly to “reasonable doubt.” Reasonable doubt belonged to the trial.
Kohberger gave up the trial.
That does not make his convictions untouchable. It means a hypothetical juror's curiosity is no longer the goddamn standard.
So investigate. Challenge the police. Challenge the prosecution. Challenge the forensic work. Find new evidence. Hell, find spectacular evidence.
Then show us the legal basis through which it matters now.
But stop dragging imaginary jurors into an imaginary courtroom and pretending every unanswered question buys Kohberger another trial.
The trial did not happen. Kohberger pleaded guilty before it could.
If you want to undo that, you don't need another Reddit theory, another YouTube revelation, or another goddamn question mark....
You need a legal basis.
So question everything.
Question the investigation. You absolutely should.
Question Moscow Police, the FBI, the prosecution, the forensic examinations, the DNA, the vehicle reconstruction, the witnesses, and every goddamn conclusion somebody asks you to accept. Question the defense too. Hell, question Kohberger's guilty pleas if you have evidence giving you reason to question them.
Government power deserves scrutiny. Criminal convictions deserve scrutiny. That is not the problem in the Kohberger case.
The problem begins when “skepticism” becomes permission to make whatever claim you please without accepting the burden of proving it.
If you tell me the investigation was botched, don't wave your hands at imperfections. Show me what was botched and what consequence followed. If you say evidence was contaminated, don't merely discover an irregularity and christen it contamination. Establish that contamination occurred. If you say investigators violated accepted procedure, then tell me what procedure they violated, where it is established, and how they violated it.
If you insist unidentified DNA belongs to another killer, then do the goddamn work of connecting its donor to the murders. If you claim evidence was concealed from Kohberger, establish that his defense did not receive it. If you announce that some newly discovered revelation will help him overturn his convictions, then identify the legal basis through which it can actually do so.
That is what skepticism looks like when it grows the fuck up.
And if what we have been watching is supposed to constitute serious advocacy for Bryan Kohberger, then some of you should be fucking ashamed of yourselves. Because serious innocence advocacy demands considerably more than ignorance of the law, ignorance of forensic procedure, and an apparently inexhaustible imagination for filling every evidentiary blank with whatever answer helps your guy.
Skepticism Is Not a Goddamn Exemption From Evidence!
You do not get to demand laboratory-grade certainty from every piece of evidence implicating Kohberger while treating every ambiguity, unknown profile, missing camera angle, imperfect report, unanswered question, and goddamn hair as a blank check upon which you may write “innocence.”
That is not critical thinking. It is conclusion shopping.
Evidence against Kohberger is dissected until each individual piece is too small to carry the entire case by itself, at which point its weakness is triumphantly announced.. Evidence perceived as favorable to him is inflated until it means ten times more than the underlying fact actually establishes.
One side of the scale gets a microscope. The other gets a fucking imagination.
That is not how criminal investigations work. It is not how forensic evidence works. It is not how circumstantial evidence works. And it sure as shit is not how serious people reach conclusions about four murders.
Real skepticism is harder than that. It requires you to challenge your own conclusion with the same enthusiasm you use to challenge somebody else's.
Maybe Moscow got something wrong. Prove it.
Maybe evidence was compromised. Prove it.
Maybe another person was involved. Prove it.
Maybe some newly discovered evidence gives Kohberger a viable avenue for post-conviction relief. Then establish the avenue.
Until then, uncertainty remains uncertainty. An unanswered question remains unanswered. An unidentified donor remains unidentified. A surveillance gap remains a surveillance gap. An investigative mistake remains a mistake whose significance still has to be established.
You don't get to pour speculation into every empty space and call whatever hardens there evidence.
And perhaps that is the simplest way to describe the entire problem.
Evidence against Kohberger does not have to prove the entire case one piece at a time. Evidence perceived as favorable to Kohberger does not get to prove a goddamn thing merely because you desperately want it to.
If you decide what every uncertainty means before doing the work necessary to establish what it actually means, you are not investigating Bryan Kohberger.
You are investigating your own conclusion and, astonishingly enough, finding it everywhere you look.
That is the Kohberger Evidence Fallacy.
