A woman suffered a vicious rape in London. There was little information to work with after the initial investigation. The victim had been drinking heavily before the attack and she believed there was little chance of the rapist being caught, let alone convicted. She seemed unable and unwilling to provide important details of what had happened.<\/p>\n
An investigative team was assembled, including one of the UK\u2019s top forensic psychologists, Professor Ray Bull. \u201cShe was understandably reticent, she didn\u2019t want to say anything that was inconsistent and that might weaken her case,\u201d says Bull. \u201cBut a lot had happened to her and we needed to work that out.\u201d<\/p>\n
Bull selected an interviewer, a young woman, whom he thought would be most effective. He listened in to the interviews and, drawing on more than 30 years of research in psychology, provided continual advice. He helped her obtain key details, some of which enabled police to connect the attack to another incident, and eventually convict a serial rapist.<\/p>\n
Investigative interviewing is at the very core of the system of justice, says Bull, and investigators must strive continually to improve what they do. \u201cIt\u2019s essential. The consequences of not being good are horrendous. This is real life – and if you get it wrong you can do a lot of damage to a lot of people.\u201d<\/p>\n
Bull conducts research on investigative interviewing of suspects, witnesses and victims, as well as witness memory and voice recognition. He shares his research and that of other academics internationally, consulting to organisations as diverse as the UK\u2019s Home Office, courts, governments, police forces and even large private companies.<\/p>\n
While investigators need to have a high level of self-belief and confidence, he says, they need to be open to accepting that they can always do better. At an institutional level, organisations need outside help and to learn from the variety of research that is now available. \u201cI spend a lot of my time going around the world training the trainers,\u201d says Bull, who was recently in Jamaica working with an internal police organisation.<\/p>\n
People are not naturally good interviewers. \u201cWhat you want in an investigation is for a person to give you lots and lots of information,\u201d Bull says. \u201cSocially, we learn the opposite – in normal conversation we ask a lot of closed and leading questions, and that can be very difficult to give up.\u201d<\/p>\n
Bull has been closely involved with the substantial changes that have taken place in the UK with investigative interviewing. In 1986, it became a legal requirement for police to record interviews, the first country to do so. It was only when these recordings were analysed that police officers themselves realised they were not interviewing well.<\/p>\n
\u201cPeople guilty of serious wrong-doing were running rings around the investigators,\u201d says Bull.
\nThat led to investment in research and the training of detectives in the mid-1990s. Today, the UK is widely considered a model of cooperation between academics, investigative authorities and the government.
\nNew research is continually challenging commonly-held beliefs, says Bull.<\/p>\n
\u201cIt\u2019s a common belief, for example, that people who have done something wrong are not going to tell you about their wrongdoing. Well, in fact, there\u2019s an increasing amount of recent and meaningful research that has come to the surprising conclusion that only about 25% of people guilty of wrongdoing will absolutely deny it.<\/p>\n
\u201cIn fact, about 50% of people who are guilty of wrong-doing are pretty open-minded about how they are going to behave, and wait to see how they are treated by investigators,\u201d says Bull.
\nInterviewers need not to have a domineering approach if they are to persuade potentially hostile suspects or witnesses to give them information. There need to be pauses and silences in the interview, and establishing and maintaining rapport with the interviewee is one of the \u201cmost essential\u201d skills to learn, says Bull.<\/p>\n
The key to a good investigation, says Bull, is the content of what people say. \u201cYou need to interview in a way that gets people talking, and then you can analyse and compare what they say with other information and that substantially increases the percentage above chance of getting to the truth.\u201d<\/p>\n
Bull started working with a major police force in the UK in 1970, helping officers with recall and memory. He\u2019s conducted research on interviewing vulnerable people and authored the first official guidance in the UK on how to interview children. He is regularly asked to provide expert reports on the quality of interviews and testifies in court on average about eight times a year.<\/p>\n
During an academic career now spanning more than 40 years, Bull has written or co-authored more than 200 academic articles and books.<\/p>\n
He received a Commendation from the London Metropolitan Police for \u201cinnovation and professionalism\u201d for his assistance with the London rape case.<\/p>\n
He has since received awards and recognition for his work from the British Psychological Society, European Association of Psychology and Law and a special prize for his \u201cextensive contributions to investigative interviewing\u201d from the Scientific Committee of the Fourth International Conference on Investigative Interviewing.<\/p>\n","protected":false},"excerpt":{"rendered":"
