4 Police Interrogation Techniques You Should Know (And Why Not All of Them Work)

When questioned about a crime, it is a pretty good assumption that the criminally-inclined will always lie: “I didn’t do it”. The irony is that good guys — people who are actually innocent — will tell investigators the exactly the same story – “I didn’t do it”.

How do you tell which one is telling the truth? And, if you apply pressure techniques, how do you keep the innocent ones from breaking down and implicating themselves by a false admission?

In court, a confession is the most trusted evidence a prosecutor can present. In some cases, a confession will explain away inconsistencies in evidence, contradictory witness testimony, and later recanted versions of the confession. If he said it, he must have done it. A satisfied police interrogator will congratulate himself for solving the case, when in fact, he may have ruined an innocent man’s life, allowed a real criminal to continue committing crimes, and cost the government a lot of money for a wrong prosecution. Later, when the truth finally comes out, the repercussions spread farther, perhaps even crashing a good cop’s career.

Are interrogations successful? You bet. When investigators began bringing in suspects for the Lindbergh kidnapping, they got over 200 confessions.


1. We’ll beat the truth out of you: the traditional method.

Historically, confessions were a simple matter of applying the so-called third degree. Depriving the subject of food, water and sleep, applying physical discomfort, beating him with a rubber hose so as not to leave marks and even threats or intimidation eventually broke a subject or caused him to accept whatever story he was being fed — simply to stop the abuse. The intimidation would also continue a bit longer, however,  in order to get the subject to sign a paper saying he had not been coerced and his statement was voluntary. With the paper in hand and a blindfold over the statue of Lady Justice’s eyes, the admission would seal the suspect’s fate.

It was not until 1937, when the court threw out a seemingly voluntary confession — obtained by officers who had strung a suspect up in a tree and repeatedly whipped him to get him to agree to perjure himself — that harsh techniques were gradually abolished.


2. We can tell yer lyin’ by the way ya blink yer eyes: the Reid technique.

The most popular modern technique for interrogation — the one that has been taught in most police academies since the 70s — is the Reid Technique, named after the Chicago policeman who developed it in the 40s. It relies on a careful  building of rapport, tests for reliability on known answers to control questions, and observation of body language to identify anxiety, which, according to Reid, is a signal for lying.

Unfortunately, according to Douglas Starr, who published and did extensive research on the method, the Reid technique relies on outdated and discredited science and unqualified psychology. 40 years of extensive psychological research has debunked the idea that anxiety connotes lying. Anxiety is a normal reaction to being in a high stress situation. Conversely, there are many liars who can look you in the eye and tell you with conviction anything they want you to believe.

A good account of the Reid process is described by S. J. Parris; “they twisted every answer I gave until it sounded like the opposite meaning, and I became so confused and afraid I found myself agreeing to statements that I knew were not true.”


3. Hey buddy, you can trust me: good cop, bad cop.

Even small children have heard of the good cop, bad cop routine, when their parents team up — one nurturing, one angry and threatening — to find out who ate the cookies (after they have already found crumbs on her tiny mattress). In a high pressure situation, many people will open up to someone offering compassion, and even go along with suggestions to ensure that the presumably nice person will continue to protect her.


4. Lies are like a house of cards: the PEACE method.

A new interviewing technique is gaining acceptance as an effective way to discover the truth without creating false witnesses. The PEACE (Preparation and Planning, Engage and Explain, Account, Closure and Evaluate) method is being applied in the UK, Denmark, New Zealand and a few other places. It resembles a journalistic approach, and is very straightforward. It assumes that a liar will gradually build up a series of false explanations, and the more the subject lies, the more he has to juggle in his mind. Eventually, an inconsistent detail will break down the whole fabrication.

As Laurie Halse Anderson says in her crime novel The Impossible Knife of Memory: “The trick to surviving an interrogation is patience. Don’t offer up anything. Don’t explain. Answer the question and only the question that is asked so you don’t accidentally put your head in a noose.”


On the other hand: the suspect’s viewpoint.

The suspect, whether innocent or not, must realize that they are playing a game of perception. They don’t want to appear to have anything to hide, and want to be seen as cooperative, so they are already open to transgressions against their rights. They may waive their Miranda rights in the United States (to stay silent unless their attorney is present) because they will be told by authorities that they don’t need that protection if they have nothing to hide. Innocent people bite on that lie almost every time. They may have faith in the justice system and — if actually innocent — they figure the truth will come out and justice will prevail.

Yet sometimes the facts may be so obtuse and convoluted, or the alibi (“I was watching TV alone at home, nobody was with me”) will not be enough to save them.  Justice will not prevail because nobody is willing to look farther for the truth once they have an admission.


Your Turn: Do you know of any other interrogation techniques that we haven’t mentioned here? Have anything else to say about the ones we’ve already covered? We’d love to hear from you. Leave us a comment.




  • Daniel G says:

    I think the main thing to remember- from the suspect’s perspective- is that the police are actually the weaker party, not the suspect. The police need info from the suspect to gain a conviction, but there’s nothing the suspect can gain from co-operating with police (unless the suspect somehow enjoys prison life), so really, the suspect has everything to lose and nothing to gain by providing information. This should give the suspect the position of strength, because the police needs them yet they don’t need the police.

    • Daniel, that is an interesting take. Sitting in that room can be pretty intimidating (have not had personal experience with that, but I think it is safe to assume here), so any insight into how the game can be played, especially for an innocent person, helps even the odds. Really, anyone finding himself in that position should consider their rights and get his or her attorney there as soon as possible.

      It’s an emotional place, designed to intimidate, and each misstep by the ‘suspect’, whether made innocently or with the intention to deceive is being recorded, watched, analyzed and compared against other things one says. So, with all of the scrutiny going on, all of the psychology, all of the pressure and certainly a difference of objectives (the ‘suspect’ is anxious to prove innocence, the police are eager to prove guilt), I’m not sure one should assume he or she has any advantage in that room.

      Also, remember that there will be other outside factors which may weigh against the ‘suspect’ – another witness ready to implicate the suspect with either truths, half truths or lies, physical or circumstantial, an unsubstantiated alibi, a single misstatement (whether in error or intentional) which casts doubt on the suspect – and many other factors. And what if the suspect is actually the perpetrator?

      Keeping your mouth shut to stymie the ‘weaker’ police is one strategy, but even then, getting into trouble is still pretty easy.

      Call the lawyer.

      • Sandeep says:

        Well, I disagree. In today’s world probability is if Law Enforcement has reached you with enough on hand to get authorisation for interrogation you are already there. What matters a lot is your side of the story. As a human being you want to hear why the perpetrator did it, even if you know how. An uncooperative statement creates a harsher perception of your actions by putting you as a calculative cold blooded criminal, hence not deserving of sympathy of the Officer.

    • Rich Haberkorn says:

      Rich says, good points Daniel, and to that I will add the following points; If the poLICE had all the info. they needed they wouldn’t even bother attempting to get you to talk in order that they can use whatever you say ‘against you’. Its always best to reserve your rights. If “your” lawyer shows up, that doesn’t mean you talk then either, simply reserve your right to ‘stand mute’ and tell the judge the same thing, if it would even get that far. Remember too, the American legal system cannot accept a forced confession, so if you had a forced confession [by whatever means], the judge cannot accept it.

      • Debbie says:

        Not necessarily. One could have all the answers, and all they need is a confession. Without the confession or anything that sounds like one the police can go nowhere with it.

      • You are wrong when you say that if the police had everything they need to arrest you they wouldn’t need to talk to you. What if it was self defense, what if the police doubt an accuser, these are just two reasons to talk nto a perp

      • Liz says:

        Cops can also tell the suspect an untrue story to get the suspect to confess. But, that is not illegal.

    • logan pitzer says:

      that is true, but the suspect has a the amendments.

    • David says:

      Sorry Daniel, but I disagree. I have many times informed the prosecuting attorney and the judge that the suspect (perpetrator of said crime) was co-operative and had positive results. Sometimes it does help the criminal. I had cases where very sentimental jewelry was recovered because the perp co-operated early and the victim decided not to prosecute. Sometimes people’s lives can be saved when the help. You cannot categorically make the statement you made and be correct. I am just flabbergasted that their are so many people out there who feel that the police are the criminals and the the criminals are the victims and that the victims are NOTHING!

  • Kayli says:

    One or two to remember, that is.

  • Jason says:

    I was interrogated at 18 years old I was intoxicated 4 times over limit I was throwing up dizzy dehydrated they refused to give me water until I said what they wanted to hear

    • Liz ;p says:

      That’s horrible. When I become a cop, then later hopefully a detective, I will never even think about doing anything like that. That disgusts me that a police officer had the audacity to abuse his/her power like that. >:( I’m so sorry for you. Luckily for me, all the cops I’ve ever met have been so sweet to me. I hope you don’t think that all cops are bad. Trust me, they’re not.

    • I do not believe that. How do you know you were four times iveer the limit? 4X would mean a .40 a few years back or a .32 now, virtually comatose for an 18 year old. You, my friend, are shooting BS!

  • Sandeep says:

    Consider this situation: White collar Crime, LEOs know perp did it, perp goes I am innocent/I did not do it/I don’t know/etc. when he is not repeating his story. On the whole, he is uncooperative, knows our limits hence not scared, aware of evidence till date. How would you go about it?

  • Piscopo Charles says:

    I was an interrogator in the US Army for 18 years, after 4 years in the Marines. If I were taken to a police station against my will in the US, there is no way in hell I would say any word or phrase except “I want a lawyer.”

  • Trusted Source says:

    No one in law enforcement is trained to give a crap if someone is innocent or not the minute you say in any training program the person might be
    innocent they will drop you from the program they want you to go in always thinking the person is guilty in Canadian law when they read you your so called rights they say can and will be used against you so you know right there they just want to convict you on anything they can not looking to really investigate anything they only care about a conviction rate

    • You are so wrong, where did you get that line of crap?? Officers are trained to have corroboration with confessions. Your blurb is rediculous and without foundation of any kind.

  • Tiffany K says:

    Does anyone here know how to obtain interrogation records? Perhaps video, audio or transcripts? I’m in Ohio and I’m looking for information regarding my father’s murder in 1991. I really don’t know where to start to try to obtain this information. It would have been from sometime in 1992. Do they release these to public record or are they destroyed after a certain time? Any help would be appreciated.

  • Liz ;p says:

    I don’t know, but I’m so sorry. Maybe if you go to the police station, you an tell them what you’re looking for and they’ll give it to you. I’m so so so so so so so so so so so so so so so sorry for you.
