the video might be shocking but it's simply a ploy used by us police offices. filming with their own cameras they inform this woman called dalia that house bill is just being killed they want to gauge her reactions as they suspect she may have hired a hit man to murder a spouse. or the like oh ok i'll try to cut. back. the camera and navigate that. in fact no killing has taken place and the police have made up the story to try and confuse dalia what they want is a confession and a few hours later she will be charged with attempted murder in this case it was the cross-examination of dalia that led to the truth and then eased the way to her 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 spec 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 bare room that disorientate suspects and allows for physical proximity. but does it work tiffany paulson son has definite views on this kind of police procedure. after a robust. well

. and you just know it's going to be a very unpleasant situation it's kind of like walking and. you walk in there and it smells of fear. lingering. before depression. everything like that. and they said. psychological.

but this time she's not being picked up. the book the good cop bad cop routine i remember the. dark complected. and had a very. 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 tof him 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 did give up. you get defensive and when you get defensive the detectives to jump on that why are you defensive then do you think only innocent people when you're trying to 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 hair and he'd be this far away from my face and i'm going to. just start saying anything else i

could say. to me claimed 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 even and 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 hemant 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 have a study claims it was self-defense off the lure of stab her in the leg left town i'm told and is put in charge of the questioning. or aether stone or laura perkins lived in the downstairs apartment heather had two children laura had basically an adopted child from a previous relationship that 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 amp used a 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 in a dome and takes have a stone into 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. with short hair and 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. pat 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. 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. if it's true. and if it. is she. will. get it. she was surprised she was surprised that we were going to smoke in here 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 . however tries to evade the questions something that intrigues the police. we. couldn't really explain where she was and where heather was i mean with susan where laura was during this whole violent struggle that apparently happens 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 leg. other claims lauren made these wounds when she stopped. in fact it's a story suggested by 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. put rings 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. right on the scene. first street. and i would think that you're. on a reporter's twitter. and instagram. to be in the know. on. wealthy british

scientists on some time. markets. come to. find out what's really happening to the global economy with mike's cars or for a no holds barred look at the global financial headlines tune in to kaiser report on r t. o v. please. please. don't speak. to. her.

which. please. mum and good luck. mum. just snip. and. run a little.

the police have there to provide more details and she falls into the trap when she tries to act out the scene. oh sure. because to do this. i'm not going to this. she said here. actually post it. here or to. the police want to force heavy into providing the exact details something they know full well is a nightmare for those who are lying it's ok sure is that. it helps everyone oh ok so allison are we willing. to give sugar. just.

because she. doesn't see it is that it's all 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. just saying. this is going to do it. she's tearing to. see this is the bullet. 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 total 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 why 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 listen joyce is already talk to us we already know everything that george has told us well we didn't know that joyce i've talked to joyce she'd like to now while we're talking to heather will reinterview injuries detective harrington who had been in here is now interview enjoys 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 lot. exhausted and betrayed by her own lying have finally caves in

after three hours. later they're. still there. is there that i understand. why 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 their 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. i'm as we're just tell the truth.

me. they went through a lot to get the truth. i went through a lot to tell them the truth i'd 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 . 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 the 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. to the bus. remember. yes or no. were you born in the month of may. did you steal that watch from the poster. 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. but it's there it's clear to see when i put a 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. dave bryant 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 banned because of it's on reliable results. steve risen is a law professor in chicago he's an expert in interrogation techniques and has been able to obtain the freedom of several suspects on death row life sentences often

their alleged confessions he's one of the polygraphs fiercest critics. they hook 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 innocent or guilty. and 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. and then i told you i had nothing to do with the 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 it's there is a simplistic and it's methods as overly coercive. all the studies show that people can deception at 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 that eighty five percent that's just hogwash but it drives the interrogation in a way that it 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 orient is body away from the interviewer in

a frontline position the 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 facts once in awhile dear and just. enjoy. the nature. of those. two and a half years later when i got arrested for. twenty eight years old. and spent eighteen a half years in prison. for a crime i did not do. apple for example much of its manufacturing is done on in the united states so i don't see why the american sanitary would be so concerned about it paying or not paying

taxes because ultimately it's not going to get any share of that and that's happening already and of course we're talking here about how do you share the taxes provided there are tox is a problem today there's no big there's share because we have grievances rigi where these companies don't break tax. i've seen the perception of the cross many times it doesn't matter if there's snow a heat wave or hail storms for people keep on going i don't expect anything just one i told myself i keep on going as long as my heart told me to that's all i wanted to the moment he had a hand send so mind she see him carrying the sains on my shoulder.

do you want me to put a bandage here no that's fine a lot of people were so exhausted they could barely walk their feet hurt and some of them fainted who were evacuated three two wanted to keep going i don't know what tomorrow will bring. you know sometimes you see a story and it seems so you think you understand it and then you glimpse something else you hear or see some other part of it and realize that everything you thought you knew you don't know i'm tom harpur welcome to the big picture. mission. pretty sure three. three. three three. three stooges three.
