Since the 1980s the federal government has prompted the militarization of federal, state, and local law enforcement. That militarization has led not only to well‐​publicized disasters, but to a widespread increase in violent law enforcement, which has played a major role in alienating Americans from their government. Such baleful consequences are the result of another dangerous trend, the expansion of the power of federal criminal justice far beyond its legitimate constitutional limits. Law and order begin at the top; the most important criminal justice reforms are those that return federal law enforcement to its constitutional role.
