ok look at that. in fact no killing has taken place and the police have made up the story to try and confuse done. and a few hours later she will be charged with attempted murder in this case it was the cross-examination that led to the truth and then eased the way to prosecution. among the police the interrogation process is considered a key element of the investigation where everything might fall into place which explains why in the united states this method of investigation has been pushed to its very limits more than anywhere else in the world how does the interrogation take place is it an exact science can you tell when the sauce is lying and can you trust the confessions.

in the united states everything is aimed at making the suspect crime from the architecture of the interrogation room it's a small room that disorientate suspects and allows for physical proximity. but does it work tiffany pawson son has definite views on this kind of police procedure. after a robust session in the interrogation room she confessed to killing her best friend on the fifteenth of april one thousand nine hundred ninety seven tiffany received a life sentence the memories of when she stepped into the interrogation room. and he smelled the granton smell and hear it. and you just know it's going to be

a very unpleasant situation it's kind of like walking into that except there is not going to be any needle to numb anything you walk in there and it smells of fear it smells of the way you pick up that lingering energy of people in there before of the depression of the id of everything it's just like the atmosphere just clings to it and they sit you in there it's psychological. at the time tiffany was twenty three years old and a prostitute she's familiar with the police and their tactics but this time she's not being picked up for soliciting but for a murder in which all the clues seem to point to her to make a confess the police will use the oldest trick in the book the good cop bad cop routine i remember the one explicitly well madden and he was tall approximately sixty to sixty four dark complected overbearing he wore jeans

a lot polo shirts and had a very cocky attitude. the other one is kind of blurry my memory of him is blurry i think he played the good cop bad was the bad cop. introducing sergeant almost seven feet tall in his socks years of experience and not the kind of cop that's easily fooled. it's about his tough questioning methods it's his whole. there is a certain amount of acting for being. for doing interviews and especially when you're in that role as far as a good cop bad cop. so for the most part one is consoling caring. you

know almost. even putting off the other detective to the suspect saying you know he's he's a very mean guy he's a bad guy or whatever the case is trying to get closer with the suspect so hopefully this is suspect confides and quote unquote the good cop. to phonies tough and for three days a constant learning drives the interrogators to destruction. she makes up stories about her movements shifts the blame onto others and dismisses the evidence that the police don't give up. you get defensive and when you get defensive the detectives team to jump on that why are you defensive and do you think only innocent people when you're trying to you thinking in terms of i say yes i need an attorney when you're saying oh you're guilty so you need an attorney is that what you're saying so it's very it's very difficult the last interview kind of switched where i was very direct i was very accusatory and i even

stormed out of the room once again some theater if you will to try to create a better atmosphere for the other detective he was very tall and very. over you all the time. overbearing and i can remember trying to like get in my chair you know and be like i'm sick of this my r.v. be this far away from my face and i go. and i just start saying anything else i could say. to me claims she acted in self-defense but it's an admission that. finds down. she never told the truth. that was that was basically the sum of it she never told the truth and even then they had so i've never told the truth.

tiffany played down her part in the murder the fact she doesn't break down under the questioning of an experienced policeman shows the limitations of the good cop bad cop method. so a fall less theatrical technique is being adopted that has found favor with many american police. it's an approach left hand and doleman fervently supports in july two thousand and six and murder rocks the usually quiet town of dover in new hampshire laura perkins is shot dead by have a star the woman with whom she lives from the start had a study claims it was self-defense off the lure of stab her in the leg left and i'm told is put in charge of the questioning. go forward as are still in a lower perkins lived in that the downstairs apartment had or had two children laura had basically an adopted child from

a previous relationship that would sometimes stay with her there two on the night in question they'd been arguing since three four o'clock in the afternoon until two morning just constant arguing while constantly drinking everybody knew that had their head shot laura the question was always going to be what are the circumstances was this a case of an abused woman protecting herself or was this a case of an angry woman killing a girl for. other students interrogation begins at six in the morning just a few hours off to the left on a dome and takes have a stone to the room set aside for the purpose a cold stock room which meets police standards. so this is the into. that morning was seated here. our camera was behind this this window right here. today behind bars. she's barely recognizable.

admitting she had not acted in self-defense. remarkably video of the interrogation was made available something that in most european countries would be unthinkable. has lied to the police about acting in self-defense. the police patiently let's have the present her version of events. if she was born for a couple reasons one she really had an obligation to provide an explanation as to

why her girlfriend is dead on the floor so she has a motivation to tell us something even if it's a lie she is mortician to talk to us she's vulnerable because she's tired she's vulnerable because she's emotional can really is upset that this happened she's not a stone cold killer by any stretch. i don't really know what i was trying to do what i was lying. pot i mean part of me thought that. they believed me and part of me said no they won't the police believe there are certain facts that don't add up they even turn to a proven tactic of gaining the trust of the suspect softening her up by taking advantage of one of the vices cigarettes. is. if you are good and if it. is.

good will. you get it. she was surprised she was surprised that we were going to smoke because it's a no smoking building in a no smoking facility well whatever you know you're going welcome a smoking or if you're going to talk to us about this part of that just occurred i'm going to let you smoke and they let us smoke in return for information. however tries to evade the questions something but intrigues the police. can. we.

couldn't really explain where she was and where heather was and where laura was during this whole violent struggle. so they were skeptical there also skeptical because the injuries she had were minor scratches to a leg not stab wounds or big slashes but just minor cuts to the way. other planes laura made these wounds when she stabbed. in fact it's a story suggested by joyce a friend she called just after the shooting joyce also helps have a change the location of the crime to add weight to her assertion she acted in self defense. put reins on him punched me in the face and then i cut my leg. we thought that would. get me so i would go to jail for.

good leverage or. was able to build a new most sophisticated. fortunately doesn't sound anything tunes mission to teach music creation why it should care about humans in the world this is why you should care only dot com. the speed.

with. all. the good. will. come out of my mind i'm a fairly. i would rather ask questions for people in positions of power instead of speaking on their behalf and that's why you can find my show larry king now right here on r.t. question more.

clearly. was telling. the police heather to provide more details and she falls into this trap when she tries to act out the scene with. the sure. student like this. i know frank this. just. should stand here will actually come. here all day and. the police want to force heavy into providing the exact details something they know full well is a nightmare for those who are lying least ok sure is that. right now and. this oh ok shall is how we will just to get.

this in to see is that it is else so emotional that i couldn't even really grasp their questions or even answer them i was trying to but i was lying at first so they knew this so they were trying to get it out of me and i was. the sole motional that. even their questions were like spanish to me. they should just say no. this didn't do it. very serious deary. do see this is. the fact that she's tired probably made it easier for us because it was it's hard to keep up a lie it's very easy to tell the truth over and over and over again the tell the truth is the truth you just tell

a story about what happened if it's the truth all you have to do is tell the truth over and over if you tell lies you have to work to tell lies you have to work to construct something that didn't happen. but after two hours of questioning the detectives know they getting nowhere and move on to plan b. they put in the joyce is the friend who suggested the self-defense ploy has confessed to everything. detective watkins and says listen george has already talked to us we already know everything that joyce has told us well we didn't know that joyce i had talked to joyce she lied to me now while we're talking to heather we're reinterview injuries detective harrington would been in here is now interview enjoys but we don't know what she said we're stuck in here with heather so that's a bit of that's that's. are frankly a lot. exhausted and betrayed by her own lying have finally caves in after three hours. believe.

there is there. then. one things they kept saying to her is she would talk about her children and she was afraid her children she would never see her children again the children will grow up without a mother and my point to her was you know what's going to look better what's going to work out better for you if you come in here and lie to us about this the death of your girlfriend or you tell us the truth. in a lie. i just think it this is it. just tell the truth.

and. then they sent one. load in that now. do. do you need to meet. they went through a lot to get the truth. i went through

a lot to tell them the truth i told them exactly. i told them. how i remembered it. but i wasn't in the right state of mind. so i don't even remember what i told them . the other says she has no regrets about having finally admitted the truth she still has twenty four years of her sentence to serve. it's every investigator's dream to get the suspect to confess after questioning the quest for the truth is a holy grail for every policeman and investigator. and since the one nine hundred thirty s. scientists have tried to create an infallible lie detector machine or polygraph. it detects human reactions through captors placed on the arms the chest the fingers

and under the buttocks. i don't remember. yes or no answer to question. were you born in the month of may. did you feel that watching the poster to. know. any abnormal physical reaction can be interpreted as a sign of lying. to find out more about polygraphs which were considered to be a form of truth serum for so many years we seek the opinion of dave bryant a florida based policeman who specializes in their use. one of the people who did research on polygraph was the guy who is better known for creating the comic books wonder woman his name was marston he was

a physician and he wrote comic books on the side and what's interesting if you know anything about wonder woman one of the tools that wonder woman had was called the lasso of truth where she would put a rope around the bad guy and that caused him to have to tell the truth well the lasso of truth that he uses is literally this the blood pressure cop that we used today that goes around the subject's arm sort of a misnomer the instrument is a polygraph instrument it's recording physiological data it doesn't detect lies anymore than cardiogram detects heart attacks it's up to me to analyze the data that i record with a polygraph instrument to determine if the person is being truthful or deceptive as you see it rise to the line that's an increase in blood pressure ok so on this question here for example this was a controlled question this is a lie the subject answered no which is why there's a minus sign there and you'll see there's

a rise in blood pressure very subtle rise in blood pressure but it's there it's clear to see when i put the line there there's a certainly an amplitude change here and also you'll see that his breathing changed from the normal respiration out here at this point he actually stopped breathing slightly during that question that's a controlled question that we know was a lie. brian defends the tool he uses for his work adding the majority of police departments and even the cia use the polygraph in europe however it's bad because of its own reliable results. is a law professor in chicago he's an expert in interrogation techniques and has been able to obtain the freedom. several suspects on death row life sentences after their alleged confessions he's one of the polygraphs fiercest critics. they hope

the person up to this machine they tell them that this machine is infallible and it's objective and it's neutral it doesn't know you this machine doesn't have any stake in whether or not you're in the center guilty. when they fail that polygraph test or better yet when they're told they fail that polygraph test it brings them down to a place of hopelessness where it's easier to get them to confess and we have numerous cases where police officers lie about polygraph results and get innocent people to confess. knowing the polygraph is not always dependable scientists have been urgently researching brain i and voice patterns instead so far without much success the human spirit seems capable of resisting even the most determined efforts to extract the truth. and to read a private company based in chicago that has set up a method based largely on human psychology. today it's the largest company in the

world dealing with interrogation techniques staffed by former detectives it has trained almost three hundred fifty thousand police officers. the company uses videos to show the one thousand and one ways to make a suspect talk. let me ask you did you force her to have sex with you no absolutely not did you take the money from the man. a man i told you i had nothing to do with a saying ok you tell me dr. were. read claims that offer it's training programs police officers will be able to spot lies in almost eighty five percent of cases it's a remarkable claim but despite its apparent success rate the company has turned down all requests to be interviewed it might be because of steve driza and other experts who severely condemn its theories a simplistic and it's methods as overly coercive. all the studies show that

people can't because section at rates better than a coin flip may be slightly better than fifty percent ok. they're leaving these training thinking that they can detect deception it eighty five percent that's just hogwash but it drives the interrogation in a way that makes it much more likely that they're going to obtain false confessions . but reid has taken note of such criticism and has improved its methodology by asking instructors to be more prudent when it comes to the signals that could be interpreted as lying nevertheless the video still teach the same controversial process of recognizing lies through body language. a deceptive suspect may orient his body away from the interviewer in a front line position the subject posture is the rigid posture suspect the so preoccupied with his deception that he appears frozen in the chair and even unable

to move the purpose of an interrogation unfortunately all too often is not about getting the truth it's about getting a confession so innocence is taken off the table and then over time the interrogator will give the suspect two choices one in which the crime that the suspect committed. portrays a suspect is a monster and another path the crime is accidental and over time after his denials are rejected over and over again the suspect will choose one of those two paths because one of those paths leads to leniency and the other one leads to greater punishment. it's a choice that allows no room for the innocent and one that frank stirling to make more than twenty years ago. i used to. see a. deer.

in the nature. back to. two and a half years later i got arrested for. twenty eight years old. and spent. half years in prison. for a crime i did not do. i've seen the per session of the cross many times it doesn't matter if there's snow a heat wave or hail stones people keep on going but i didn't expect anything just one i told myself i keep on going as long as my heart told me to watch that so i

want to get the moment mickey i have seen so much you see i'm carrying these sayings on my shoulder. do you want me to put a bandage beard you know that's fine but a lot of people were so exhausted they could barely walk their feet hurt and some of them fainted we've already back to it three two wanted to keep going i don't know what tomorrow will bring. do we speak your language as i think about the war not a day of. news programs and documentaries and spanish what matters to you breaking news a little turn to to angola's kid stories. are you here to. detroit altie spanish find out more visit. all tito it's called.
