DNA in the Courtroom: Principles and Practices
DNA in the Courtroom is the first step-by-step guide to this crucial new tool for the successful investigation and prosecution of crime. It introduces readers to the biological principles of DNA and emphasises the importance of the chain of custody and pre-trial disclosure. It also looks at the process that a DNA-sample must undergo before a DNA test result can be produced, as well as an explanation of test result interpretation. The meaning of a DNA match and aspects of population genetics, statistical calculations and DNA databases is explained. The book is user-friendly and can be used by prosecutors, defence counsel and presiding officers with equal success.
