Technology has changed the way we communicate with each other, for better or for worse. The result is that most criminal investigations now involve some aspect of digital communications evidence - be it mobile telephones seized from suspects, call data obtained from mobile network operators, or records taken from social media platforms.

This book is for practitioners looking to understand the most common types of digital communications evidence used in criminal prosecutions. From cell site mapping through to mobile telephone extraction, each category of evidence is explained and the relevant law set out. The uses and limitations are explored, as well as a focus on how best the evidence can be presented or challenged before judge and jury. Although primarily aimed at junior advocates and litigators, it is also intended to be a quick reference guide for those more senior.

Part One contains a chapter on each category of evidence, covering: Mobile Telephone Extraction, SIM Card Extraction, Call Data Records, Subscriber Checks, Cell Site Evidence, IP Address Resolution, and Intercept Material. Part Two deals with the relevant notices and warrants under RIPA 2000 and IPA 2016. Part Three is focused on disclosure: how it should be managed, what review tools are available, and how complainants should be treated.
