When Police Ignore the Evidence That Clears You: Dispelled Suspicion and Exculpatory Facts

My client asked the deputies to give him a breathalyzer. They refused. He explained, calmly and more than once, that he was a welcome hotel guest simply waiting on a room key. They ignored that too, and arrested him for being too intoxicated to care for himself while looking at a man who was standing upright, speaking clearly, and making complete sense. The case resolved for $100,000.

I have spent years suing police officers who cross constitutional lines, and one pattern shows up over and over. An officer decides early, and often wrongly, what happened. From that moment on, every fact that fits the theory gets written down, and every fact that contradicts it gets waved away. The person’s explanation becomes “just an excuse.” The evidence that could clear them becomes “not necessary.” That is not investigating. That is building a case by subtraction.

The short answer

Police have to look at the whole picture, not just the parts that support an arrest. Two related rules make that real. First, suspicion is not frozen at the start of an encounter, officers have to keep reassessing as new facts come in, and when those facts dispel the original suspicion, the detention has to end unless some other lawful basis exists. Second, probable cause can dissipate. If the facts that justified an arrest fall apart before or during it, the person cannot be arrested, or has to be released, unless officers have a separate valid basis to hold them.

Officers cannot cherry-pick the facts that incriminate someone while ignoring the ones that clear them. There is a real limit here too: once genuine probable cause exists, police don’t have to chase down every possible defense or investigate every claim of innocence. But that is a different thing entirely from looking away from obvious exculpatory evidence that is already sitting right in front of them.

GREG KIRAKOSIAN’S LEGAL EYE VIEW

Here is what actually matters in these cases: officers are allowed to be wrong at the start of an encounter, that’s what the encounter is for. What they are not allowed to do is stop looking once the facts start pointing the other way. When I take a case like this, I build a timeline of exactly what the officer knew at each minute, then show the moment the facts should have changed their mind and didn’t. That gap, between what they saw and what they wrote down, is usually the whole case.

What happened: two labels from a phone call, and everything that contradicted them

On March 27, 2024, Sky Miller was a guest at the Catalina Canyon Inn in Avalon, on Catalina Island. He and his girlfriend, who held the room reservation, had argued, and she had left. The front desk needed her permission before issuing Sky a new key. She gave it, and the receptionist was already preparing the key. Hotel staff had described Sky to the Sheriff’s Department as “belligerent” and “drunk” when they called, but by the time deputies arrived, staff had also told them the fact that should have framed the whole encounter: Sky was still a welcome guest.

From the moment Deputy A. Evans and Sergeant V. Durante engaged with him, the encounter produced fact after fact pointing away from any danger to himself. Sky greeted the deputies politely. He was on the phone and ended the call when asked. He accurately explained the key situation and said he wanted to go to his room and sleep. He stood on his own the entire time, never stumbled, never leaned on anyone. He knew where he was and what he needed, and he asked coherent, legally relevant questions.

Then there was the evidence that could have settled the question objectively. According to the complaint, Sky repeatedly asked the deputies to administer a breathalyzer. They declined. The complaint further alleges that later, at a medical facility, Sky asked for a blood test for alcohol, and that the deputies told medical staff not to perform it and warned him that continuing to push for the test could mean another night in custody.

I want to be precise about what that refusal does and doesn’t prove. Police are not automatically required to give a breathalyzer or blood test to every person accused of intoxication, and a refused test doesn’t create its own separate constitutional violation. But the deputies’ entire justification for the arrest was that Sky was too intoxicated to care for himself. An objective test could have supported that theory or destroyed it. Refusing the very testing that could confirm the accusation, while ignoring everything Sky’s own conduct was showing them, is the kind of fact that can support an inference that the stated justification was pretext, not a genuine belief. The deputies were not short on information. They had two labels from a hotel phone call, “belligerent” and “drunk,” and they built the arrest around those labels while disregarding what their own eyes, their own ears, and the man standing in front of them were telling them.

The rule in plain English

Picture a referee who only calls fouls on one team. That is not neutral officiating; it is choosing the outcome before the game starts. The Fourth Amendment does not let officers run an encounter that way. An officer can absolutely form an initial suspicion. But as the encounter unfolds, the officer has to stay open to facts that confirm or contradict it, because the whole point of stopping and questioning someone is to find out what’s actually happening to confirm the suspicion or put it to rest. When the facts put it to rest, the detention has to end unless a separate lawful reason takes its place. An officer who has already picked an outcome and simply filters out everything that doesn’t fit isn’t investigating anymore. He’s defending a conclusion. The law has names for the two failures in Sky’s case: dispelled suspicion, and dissipated probable cause.

The law behind it

The Ninth Circuit, which covers California, has made clear that suspicion isn’t measured once and locked in place. In Thomas v. Dillard, 818 F.3d 864 (9th Cir. 2016), the court held that even facts that might initially support reasonable suspicion do not justify an intrusion once additional facts dispel or negate that suspicion. The officers in that case were responding to a possible domestic-violence report, but the alleged victim denied a fight had happened and the person they confronted was cooperative and nonthreatening, the court said those later facts mattered. The same idea goes back decades, to United States v. Thomas, 863 F.2d 622 (9th Cir. 1988), where once officers could see a driver didn’t match a suspect description, the original justification for the stop fell away.

That duty to keep reevaluating continues past the initial stop, all the way through an arrest. Probable cause is not permanent. In Nicholson v. City of Los Angeles, 935 F.3d 685 (9th Cir. 2019), the Ninth Circuit held that a person may not be arrested, or may have to be released, once previously established probable cause has dissipated. Los Angeles police in that case believed a teenager was being held at gunpoint. When officers arrived, the supposed weapon turned out to be a plastic toy gun with a bright orange tip, and the teenagers were simply getting ready for school. Those facts undermined the original theory completely, yet the plaintiffs stayed handcuffed for roughly five hours, well past the point probable cause had dissolved. The court held that officers cannot continue a detention while ignoring facts that destroy its own justification.

Thomas v. Dillard also supplies the cherry-picking rule directly: officers may not select only the facts that justify an intrusion while screening out the facts that undermine it. The Ninth Circuit has likewise recognized, in Broam v. Bogan, 320 F.3d 1023 (9th Cir. 2003), that an officer isn’t protected when exculpatory evidence that would defeat probable cause is deliberately disregarded. And there’s a real boundary on all of this: Baker v. McCollan, 443 U.S. 137 (1979), holds that once genuine probable cause exists, police don’t have a constitutional duty to independently investigate every claim of innocence or chase every possible defense.

Why the deputies’ theory doesn’t survive their own record

Line Sky’s encounter up against that framework and the pattern is obvious. Deputies arrived with two secondhand labels. Then they encountered a man standing steadily on his own, speaking coherently, confirmed by the hotel as a welcome guest with a room already being prepared for him, and offering to take an objective test that could settle the question either way. In Nicholson, the orange-tipped toy gun was the fact that should have changed the officers’ minds. In Sky’s case there wasn’t just one such fact there were several, and the argument is that the deputies proceeded as if none of them existed. That is exactly what the Ninth Circuit has said the Constitution forbids: building an arrest by keeping the facts that accuse someone and discarding the facts that would clear them.

How I proved it

The strength of this theory was that I did not have to supply the exculpatory facts from outside the encounter the deputies documented them, admitted them, or captured them on their own body cameras. The footage showed Sky remaining upright, speaking clearly, explaining an ordinary hotel-key problem, asking coherent questions, and wanting to get to his room. In depositions, the deputies acknowledged he did not stumble, did not lean on anyone, and understood exactly where he was and how the key process worked. Sergeant Durante admitted there were “no specific facts” showing Sky was a danger to himself only, in his words, the general possibility of harm that he acknowledged always exists. Deputy Evans’s own report reduced the justification to the smell of alcohol and the fact that Sky repeated himself. Put that together with the alleged refusal to test him objectively when he asked, twice, and you have a record built almost entirely out of the deputies’ own words and cameras.

What an officer can and cannot do

• Can form an initial suspicion based on a witness report, a dispatch call, or what they observe, and can act on it briefly to investigate.
• Can decline to administer a breathalyzer or blood test there is no freestanding constitutional duty to test someone who requests it.
• Cannot continue to detain or arrest someone once the facts they’ve gathered dispel the suspicion that justified the stop, absent a new, independent lawful basis.
• Cannot cherry-pick facts, keeping only what supports an arrest while disregarding cooperation, coherence, witness confirmation, or an offer of objective testing.
• Is not required to investigate every claim of innocence once genuine probable cause exists, but cannot deliberately look away from exculpatory evidence already in front of them that would defeat it.

What to do if this happens to you

• State your explanation clearly and calmly, once or twice. You want it on the record, not repeated into an argument.
• Point out, calmly, any evidence that supports you: a witness nearby, a document in your hand, a camera, a key, a record confirming your account.
• If you’re accused of intoxication, you may calmly request a breathalyzer or similar test. The officer isn’t required to give you one, but note that you asked and how they responded.
• Do not physically resist, even if the stop or arrest is clearly unlawful. That fight belongs in court, not on the sidewalk.
• Remember or record officer names, badge numbers, witnesses, and the order of events, including what you asked for and what was refused.
• Watch the deadlines afterward. Claims against California public entities can require a formal government claim within six months, and separate limitations periods apply to federal and state civil rights claims. Don’t wait to have them evaluated.
