Career Details
David joined the Home Office Forensic Science Service in 1970. He worked exclusively at their specialist document examination laboratories in Cardiff (1970 to 1973) and Birmingham (1974 to 1992), and reached the rank of Grade 7 (principal scientific officer) on the grounds of personal merit.

I n 1992, he resigned from the Forensic Science Service and established Document Evidence Ltd together with six other colleagues from the Home Office. Document Evidence is one of the largest private forensic science organisations in the UK and he is a director of that company.

During the course of his career he has examined thousands of cases involving tens of thousands of documents. He has expertise in all aspects of forensic document examination including handwriting, signatures, typescript, photocopies, counterfeiting, paper, ink and impressions. He has given evidence in court on hundreds of occasions.

Most of his experience has been in the field of criminal prosecution, but he also has dealt with many other categories, including civil, commercial, criminal defence and historical documents. Cases of national interest in which he has been involved include the appeals of the so-called Birmingham Six and Guildford Four, and the Broadwater Farm appeal. Historical cases include the authentication of the diaries of Roger Casement and Josef Goebbels. He has given evidence in Ireland, California and Australia as well as the UK.

He now has over thirty years experience as a Forensic Document Examiner. He is a member of the Forensic Science Society and is an Examiner for their Diploma in Document Examination.

During his time with the Forensic Science Service, he assisted with the training of document examiners, both permanent recruits and visitors from overseas on short training courses. He is now involved with the recruitment and training of scientists for Document Evidence, and regularly assesses their work. Document Evidence operates a Quality Assurance programme and he is involved with this on a daily basis.
