The use of informants has been described as the "black hole of law enforcement." Failures in the training of police officers and federal agents in the recruitment and operation of informants has undermined costly long-term investigations, destroyed the careers of prosecutors and law enforcement officers, and caused death and serious injuries to innocent citizens and police. In many cases, the events leading to disaster could have been avoided had the law enforcement agency followed the time-tested procedures examined in this book.
