This article addresses the numerous ways command or coercion is used by the state to enhance law enforcement, ways that involve creative interactions with both the targets of law enforcement and third parties. Coercive measures encompass both mandatory reporting and mandatory action. Examples are given and the benefits of using coercion in such circumstances discussed. However, coercion may also have unintended consequences and impose unreasonable costs. With these effects in mind, the authors suggest a set of guidelines for evaluating the appropriateness of coercive measures.
