Book Description: In recent years, law enforcement has suffered a number of tactical fiascoes. Besides the loss of life and deterioration in public confidence, officers and agencies have been the subject of both civil and criminal sanctions. Unlike most tactical books, which teach tactics as a "skill set", this book emphasizes an intuitive application of funamental principles. These principles have evolved over centuries of tactical operations and form a body of "sound doctrine". Heal not only presents a distillation of the more than ninety tactical texts, but provides an insightful and compelling call for rethinking tactics of law enforcement. Assuming no prior experience or understanding of tactical matters, Heal draws from everyday life such as competitive games, driving, or planning a vacation to show how to reconceptualize a difficult situation. Because the fundamental concepts Heal explores apply to all types of emergenices, Sound Doctrine is suitable for not only law enforcement, but firefighters, private security, and other emergency responders.
