He baffled and eluded law enforcement officers for nearly two decades. In the end, however, it wasn't the painstaking forensic analysis of hundreds of pieces of crime scene evidence that led to the capture of the Unabomber-but the lucky tip of an informant. Truth of the matter is, for all their sophistication and hi-tech science, crime-fighting techniques such as fingerprint and DNA analysis are a factor in less than one percent of all criminal cases. In the overwhelming number of crimes, informants have provided the necessary ammunition needed to bring criminals to justice, from Genovese to Gotti and Capone to Dillinger. Confidential Informant: Understanding Law Enforcement's Most Valuable Tool explores the covert and clandestine world of informants-revealing the secrets of how to find them and make the most out of them, while at the same time, avoiding the pitfalls of dealing with them. Using case studies in which informants played key roles in solving crimes, the book examines all aspects of informant development and management, from the motivation of the informant to the legal problems that accompany the use of informants in criminal cases. Written by John Madinger, a former narcotics agent, supervisor and administrator, and currently a Senior Special Agent with the Criminal Investigation Division of the Internal Revenue Service, Confidential Informant: Understanding Law Enforcement's Most Valuable Tool examines the emotional and behavioral characteristics of the informant, as well as the psychology of trust and betrayal. The book also illustrates techniques for improving interviewing and communication skills when dealing with informants, and provides invaluable forms that can be used in connection with these vital sources of information.

Domestic drug enforcement takes many forms, from the rural patrol officer who happens upon a small-scale mobile “shake and bake” methamphetamine lab during a routine traffic stop, to the city narcotics detective who initiates a low-level buy-bust operation that nets a few hits of crack cocaine on the street corner, to the local, state, and federal agents working in multiagency task forces that coordinate a sting operation that nets thousands of kilos of near-pure cocaine being transported by tractor-trailer. Regardless of the form, there is a high probability that these authorities have exploited access to known offenders and exerted pressure on those individuals to gather inside information on illicit drug sales. These confidential informants provide intelligence on the inner workings of drug operations in exchange for leniency or remuneration, providing a relatively cheap source of intelligence that fuels much of the ongoing war on drugs. In other instances, law enforcement authorities will reach out to members of the criminal underworld who are willing to provide valuable intelligence in exchange for money. Despite the central role of informants in contemporary police operations, little is known about the shadowy relationships among law enforcement, snitches, and offenders. Based on ethnographic fieldwork in the narcotics, homicide, and street-level vice operations in two major metropolitan police departments, Speaking Truth to Power takes readers to the front lines of the war on drugs to unravel this complex web of information exchange.

2010 Honorable Mention, Silver Gavel Award, American Bar Association Uncovers the powerful and problematic practice of snitching to reveal disturbing truths about how American justice works Albert Burrell spent thirteen years on death row for a murder he did not commit. Atlanta police killed 92-year-old Kathryn Johnston during a misguided raid on her home. After being released by Chicago prosecutors, Darryl Moore—drug dealer, hit man, and rapist—returned home to rape an eleven-year-old girl. Such tragedies are consequences of snitching—police and prosecutors offering deals to criminal offenders in exchange for information. Although it is nearly invisible to the public, criminal snitching has invaded the American legal system in risky and sometimes shocking ways. Snitching is the first comprehensive analysis of this powerful and problematic practice, in which informant deals generate unreliable evidence, allow criminals to escape punishment, endanger the innocent, compromise the integrity of police work, and exacerbate tension between police and poor urban residents. Driven by dozens of real-life stories and debacles, the book exposes the social destruction that snitching can cause in high-crime African American neighborhoods, and how using criminal informants renders our entire penal process more secretive and less fair. Natapoff also uncovers the far-reaching legal, political, and cultural significance of snitching: from the war on drugs to hip hop music, from the FBI’s mishandling of its murderous mafia informants to the new surge in white collar and terrorism informing. She explains how existing law functions and proposes new reforms. By delving into the secretive world of criminal informants, Snitching reveals deep and often disturbing truths about the way American justice really works.
