Lyman (criminal justice, Columbia College of Missouri) provides plenty of detail in this combination instructional text and reference, describing sound drug enforcement practices in initiating investigations, securing sources of information (including other governmental agencies), conducting undercover and surveillance operations, identifying drug evidence, managing informants, dealing with clandestine laboratories, and running special enforcement operations such as curtailing air smuggling and inside growing. Lyman includes new chapters on drug enforcement for the patrol officer and legal issues of drug enforcement and material on drug courier profiling high-tech surveillance, drug diversion by doctors and drug companies, and serving high-risk warrants.
