Overcriminalization is a serious problem that has led to questionable prosecutions and injures the public interest. Thousands of criminal laws are scattered throughout the federal criminal code, and hundreds of thousands of regulations are supposed to implement those laws. In addition, the whole notion of consciousness of wrongdoing in the criminal law has been obscured. Because prosecutors have no incentive to change a system that rewards their excesses, revisions may have to come from Congress—itself the source of much of the problem, both in the laws it passes and in the standards it uses to measure prosecutorial success. If we are to take pride in the claim that we are a nation governed by law, the criminal law must be sensible and accessible, not simply a trap for the unwary.
