The USA PATRIOT Act has sparked intense public debate, with proponents claiming that the Act is a necessarily hard-minded response to a national crisis, while opponents see unwarranted, even opportunistic, expansion of state power. Perhaps no provision of the Act has generated more controversy than §215, which authorizes the FBI to seek a court order compelling the production of “any tangible things” relevant to certain counterintelligence and counterterrorism investigations. Like many other provisions of the USA PATRIOT Act, §215 will expire on December 31, 2005, unless reauthorized by Congress. The controversy, therefore, is likely to intensify over the coming months.
