Science and technology have transformed criminal investigation techniques. Computers allow police instant access to vast amounts of information, while DNA profiling, which allows an identity to be established from the tiniest scrap of evidence, represents a huge advance in forensic science. This book also examines:
fingerprints and ballistics
CCTV and surveillance techniques
the use of Tasers and other non-lethal devices
techniques for locating and identifying dead bodies
crime fighting in the future - identity cards, databases and bomb-seeking bees
