c.n.n. just saying. this is going to do it. yes we need. a very. very . steering 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 tell the truth is the truth you just tell a story about what happened if it's the truth 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 george has already

talked 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 when joyce 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 life have finally caves in after three hours. later that year to feel better. is there that i understand. 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 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. in the law.

i just figured this is it. just tell the truth. will.

do. they went through a lie 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 . the other says. he has no regrets about having finally admitted the

truth she still has twenty four years of a sentence to serve. it's every investigator's dream to get the suspect to confess off the 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 bus i. remember. yes or no answer to question. were you born in the month of may. did you feel that watching the post. know. 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 cuff 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 any more than a 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. 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 bad because of it's on reliable results. steve tourism 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 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 it doesn't have any stake in whether or not you're in the center 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 offices. 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 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 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 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 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 is body away from the interviewer in a. position 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 needs 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. dear. in the nature. of four. twenty eight years old. and spent.
