What part does the U.S. government play in criminal cases?
The most commonly used powers to support federal criminal legislation are the commerce power, the taxing power, and the postal power. While Congress has used these powers all along to define crimes, there has been an explosion of federally created crimes in the last half of the 20th century. Most of the laws controlling white-collar crime, like the RICO Act and the Victims and Witnesses Protection Act have been passed since 1950. In addition, Congress has become increasingly involved in the “war on drugs” with the creation of various drug statutes. Due to the severity of the penalties, often, local prosecutors prefer to have drug charges prosecuted in federal court rather than file state charges. Most federal laws have as their rationale that the particular crime addressed needs a uniform response nationwide, and due to the nature of drug crimes (particularly distribution), it is difficult to prosecute drug crimes on a state-by-state basis. Examples of successful federal criminal legislation are federal gun laws and federal computer laws. The federal gun laws provide uniformity and the federal computer laws make it possible to punish Internet crime.
