Now in its second edition, this volume takes a scholarly approach to an often misunderstood and controversial law enforcement investigative technique that traditionally has been shrouded in secrecy. Written by a former Miami vice and narcotics detective, DEA agent, and attorney, this authoritative book is based on boots-on-the-ground experience. Revisions to this edition include extensive updates to each chapter, discussion of sweeping changes in the FBI's informant program, addition of high-profile cases, and updated references. Featured topics include immigration reform, the irresponsible use of informants and lawsuits, whistleblowers, cooperation fees, the management of informant-driven search warrants, and fabricated information-- Provided by publisher.
