"This problem-oriented guide for police focuses on drug dealing in privately owned apartment complexes. It clearly distinguishes between open- and closed-drug markets, provides information on what is known about each market type, and offers questions to ask when analyzing each market. It also proposes various responses designed to closed-drug markets and provides a full range of problem-specific measures to determine the effectiveness of those responses."
