Eric Shepherd.

Given that Intersol’s greatest asset is its consultant practitioners and consultant academics, Eric Shepherd – working in collaboration with Mick – is responsible for ensuring we have a quality control AND continuing professional development infrastructure to ensure consistency of consultant practice and service delivery.
A former Royal Marine AND Intelligence Corps officer (specialising in interviewing, applied language work, and information analysis) Eric qualified as a forensic psychologist, a counselling psychologist, and as a psychotherapist. Over a period of 35 years he has held a wide range of academic, clinical, institutional, business, advisory, consultancy, operational, developmental, and training appointments.
Throughout this time he has worked extensively with the police service and policing bodies in UK and across the world, the legal profession (acting as an expert witness for the Crown Prosecution Service and for the defence – in cases before first instance courts and the Court of Appeal both in UK and in Ireland).
After working initially with the Metropolitan Police on the development and implementation of Human Awareness training, he became Consultant Psychologist to the City of London Police in 1983. Here he devised Conversation Management (CM) an ethical, reflective, open-minded approach to investigative interviewing. The purpose of CM is simple: to facilitate maximum disclosure of information through mindful, managed conversation. CM is the complete opposite of confession-focussed interrogation: burdensome questioning founded upon a presumption of guilt aimed at inducing the individual to say things that he or would not otherwise say, or not to say things that he or she otherwise would. Merseyside Police – the first force in UK to have electronic recording in all police stations – adopted CM and in 1985 established its Interview Development Unit co-directed by Eric – as a centre for training practitioners and trainers from UK and across the world.
In 1990 Eric was an early member of a Home Office working group laying down the foundations for PEACE: the national model for investigative interviewing, introduced in 1993 and based on CM. He worked with Kent Police on the design and delivery of Advanced Investigative Interviewing courses from 1993 until 2010. Eric has contributed to practitioner and trainer courses throughout UK including the National Crime Faculty, Metropolitan Police, GMP, West Midlands, Lancashire, Sussex, Surrey, South Wales Police, Hertfordshire, Avon and Somerset, Devon and Cornwall, Hampshire, Wiltshire, Gloucestershire, Thames Valley, Staffordshire, West Mercia, Essex, City of London Police, PSNI, and British Transport Police. He contributed to early developments in the application of interactive video in the delivery of investigative interviewing training.
Eric worked with the defence in a landmark Court of Appeal case (R v. Miller, Paris and Abdullahi, 1992) against the murder conviction of an intellectually disadvantaged man interrogated repeatedly over a period of five days, and subjected to thirteen different coercive techniques. The Royal Commission on Criminal Justice subsequently invited to Eric to give evidence on police questioning methods. He joined the Law Society’s Working Party on Police Station Practice and subsequently authored Police Station Skills for Legal Advisers and co-authored Active Defence (with Roger Ede). He advised on how to question children in court for the NSPCC training video A Case for Balance: demonstrating good practice when children are witnesses (1997).
A range of government departments (including the Home Office, Ministry of Defence, the Serious Fraud Office, and HM Revenue and Customs within the UK, and An Garda Siochana, Enterprise Ireland and the National Standards Ireland within the Irish Republic) have also used his services. Since 1997 up to the present he has worked extensively in the development of managers and practitioners in the investigation of fraud and corruption in financial services sector (insurance and banking), telecommunications (mobile phone providers), and the petrochemical sector (oil and gas industries). As Professor of Investigative, Security and Police Sciences at the City University, London Eric was involved in collaborative developments within the field of investigative interviewing in UK (with particular reference to special circumstance interviewing, e.g. counter-terrorism), Norway, and the European Union (with particular reference to the implementation of ethical interviewing, e.g. in the Baltic states and Bulgaria, and economic crime, e.g. training members of the European Anti-fraud Office (Office européen de lutte antifraude). He was involved in the development and creation of “blended learning” approaches to developing investigative interviewing knowledge and skills – combining the use of VLE (initially Blackboard and then Moodle) with “face-to-face” training. He contributes to courses at the City of London Economic Crime Academy and to Fraud Advisory Panel seminars.
Eric parallels his development work with operational practice fulfilling investigation manager, investigator, and investigative interviewer roles particularly in fraud, corruption and regulatory contravention cases. Eric continues to train police officers on advanced suspect investigative interviewing courses and in the field of economic crime. He is on the International Criminal Court roll of expert witnesses, being most recently involved in analysing the conduct, management and outcome of investigative interviews in respect to alleged genocide.
Throughout his diverse, multiple careers Eric has been a passionate change agent. In every working context he has advocated change as a constant process (not a project) and the need to create a change platform to sustain continuous improvement in the working world and practices of individuals, working groups and entire organisations. He has trained and lectured extensively on systems approaches and the application of lean thinking and lean practice.
He is author of Investigative Interviewing: the Conversation Management Approach (Oxford University Press) – now in its second edition co-authored with Dr Andy Griffiths (formerly Detective Superintendent in Sussex Police). He co-authored Analysing Witness Testimony (OUP) and Witness Testimony (OUP). Institutions throughout UK and worldwide, in both public and private sectors, have increasingly adopted Conversation Management and associated psychology-based tools developed by Eric.

- BASELINES – a tool for monitoring and identification of transient changes in interviewee behaviour.
- ASSESS+ – a tool enabling collation and assessment of anomalies in disclosures and interviewee behaviour.
- DEAL – a method for controlling inappropriate behaviour in any verbal exchange.
