The much-debated “war on drugs” has fostered many initiatives that seek to reduce the availability, distribution, and use of drugs through education, aggressive law enforcement, prosecution and incarceration, and treatment for those who abuse drugs. Law enforcement officers and, in fact, most people in the United States, understand that conquering the substance abuse problems that face our society entails a multifaceted approach through cooperative efforts. This book, Drug Interdiction: Partnerships, Legal Principles, and Investigative Methodologies for Law Enforcement , does not address society’s ills in the psychological or social context but simply provides a real-world view of law enforcement efforts geared to making a difference in fighting the “war on drugs.”
