in the united states everything is just making the suspect from the architecture of the interrogation room it's a small disorientate suspects and allows for physical proximity. but does it work. has definite views on this kind of police procedure. 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. the interrogation room. and hearing and you just know it's going to be

a very unpleasant situation as kind of like walking into that except there's not going to be any. you walk in there and it smells of fear. pick up that lingering energy. of people in there before depression. everything is just like the atmosphere. and they said their. psychological. at the time tiffany was twenty three years old prostitute she's familiar with the police and their tactics but this time she's not being picked up for soliciting for a murder in which all the clues seem to point to her. the police will use the oldest trick in the book the good cop bad cop routine i remember the one. and he was tall approximately six two to six 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 he makes new bones 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 that suspect so hopefully this is suspect confides and quote unquote good cop. to phonies tough going for three days how constant lying 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 then do you think only innocent people being attorney you thinking in terms of i say yes i need an attorney then 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 maybe like i'm sick of this my r.d. be this far away from my face and i'm going to. and i just start saying anything else i could say. to me claims she acted in self-defense but it's an admission that. 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 far less theatrical technique is being adopted that has found favor with many american police. it's an approach left handed doleman fervently supports in july two thousand and six a 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 of the study claims it was self-defense off the lure of stab her in the leg left on i'm told and is put in charge of the questioning. or aether stone or laura 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 heather had shot lor 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 murder 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 interview room that we spoke to the stone that morning heather was seated here. our camera was behind this this window right here. today behind bars seven years on with short looking tired 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 a present her version of events. she was born to 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 has motivation 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 then 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. it. if it. is.

the will to. get it this is. 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 small container 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 . had a however tries to evade the questions something but intrigues the police. we . couldn't really

explain where she was and where heather was going where laura was during this whole violent struggle. so they were skeptical they're 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 claims laura made these wounds when she stabbed. in fact it's a story suggested going to joyce a friend she called just off to the shooting joyce also helps have a change the location of the crime to add weight to her assertion she acted in self defense. he put rings on him punched me in the face and then i cut my leg. we thought that would. get me so i wouldn't go to jail.

meanwhile in vietnam who cock out the former general director bank financial faces the death penalty for embezzling five hundred thirty three billion dong. that's about twenty five million dollars chopped up for cock and now also this week a former us benefits i confess to complaining or committing some horrific deadly money printing sins many more dogs than five hundred thirty billion were embezzled from the american people according to andrew who are good men to a gruesome bond buying spree that had financially butchered main street america their bloated carcasses fed to the gluttonous changers in the river of devils on wall street i'm sorry said the repentant quantitative easing. right on the scene. first for you and i think pictures.

on our reporters twitter. and instagram. to be in the know. on. the speech or language. programs and documentaries in arabic it's all here on. reporting from the world's hot spots fifty i p interviews intriguing stories for you. in trying. to find out more visit our big teeth dog called. the olympic torch is on its epic journey to such. a one hundred twenty three days. through two thousand nine hundred ton two cities of russia. relayed by

fourteen thousand people or sixty five thousand killings. in a record setting trip by land air sea an outer space. a limp a torch relay. m r t r g dot com. the police have a to provide more details and she folds into those traps when she tries to act out the scene. so. i'm a blank this. she said. here. actually . here. the police want to force have into providing the exact details something they know full

well is a nightmare for those who are lying meat or fish or is that. it out. ok so how does how we will just to fish or get my flu. this is serious 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. sol motional that. even their questions were like spanish to me. this is c.n.n. just saying. this is going to do it. in somehow so not a very serious dearie to. 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 tows 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're 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 let's. george has already talked to us we already know everything that george has told us we didn't know that joyce i've talked to joyce she'd like to now while we're talking to heather we're reinterview interested tech that harrington who'd been in here is now interview

enjoy but we don't know what she said we're stuck in here with have so that's a bit of that's that's quite frankly a lie. exhausted and betrayed by her own lying have finally caves in after three hours. is there then. one of the things i 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.

i just figured this is it. and as we're just tell the truth. yes. loathe it now.

you. do. 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 market may. refuse to be over after watching the post. no. any abnormal physical reaction can be interpreted as a sign of lining. up 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 brandt a florida based policeman who specializes in they 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 while 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 a 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. defends the tool he uses for his work adding the majority of police departments and. when the cia used the polygraph in europe however it's banned because of its own reliable results.

steve tourism is a law professor in chicago is an expert in interrogation techniques and has been able to obtain the freedom of several suspects on death row life sentences often very ledge 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 that 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 innocent or 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 the saying ok you sell 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 its methods as overly coercive. all the studies show that people can deception rates better than a coin flip may be slightly better than fifty percent ok. they're leaving these trainings 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 all ski 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 orientals body away from the interviewer in a. position the subject posture is the rigid posture suspect the so preoccupied with this 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. deer and just. enjoy. the nature. i don't know. two and a half years later when i got arrested for. twenty eight years old. and spending eighteen a half years in prison. for a crime i did not do. if

you are targeting only one scapegoat that would be responsible five with you say that you think the banks the commercial banks then what about the non banks what about the highly leveraged institutions nor a responsible old school what about the fights so what about all the special vehicles so you see it's more. you know him banks are the main reason the bad banking system is the main reason that triggered the banks. of the whole and the entire pool as responsibility including the way us computed the account to the accounting will. of course also all the rating agencies of course the anti bank and non-banks and the

naive belief that we where you know were real there was automatic self correction of the market themselves the theory of efficiency of markets was also bought all the schools.
