Recent tragic events have brought about a rapid reconsideration of the legal restrictions placed on law enforcement and the intelligence communities. On October 26, President Bush signed into law the USA Patriot Act (Patriot Act), which makes significant changes in the legal structure within which the law enforcement and intelligence communities operate. This article focuses on the key provisions of the Patriot Act that pertain to electronic surveillance and intelligence gathering. Notwithstanding the haste with which Congress acted, the provisions of the new law relating to electronic surveillance, for the most part, are a sound effort to provide new tools for law enforcement and intelligence agencies to combat terrorism while preserving the civil liberties of individual Americans. Some changes simply update our surveillance laws to reflect the fact that we live in a digital age. Other sections expand the surveillance powers of our law enforcement and intelligence communities in ways that make sense in light of the new threats facing our country.
When we decide, however, to expand surveillance powers to track terrorists, all residents, not just the terrorists, are affected. A common problem running through many of the new authorities contained in the Patriot Act is the reliance on executive branch supervision rather than meaningful review by a neutral magistrate of the potentially highly intrusive surveillance techniques that are authorized. There are several common sense changes that could be made to the new law that would provide better protections for civil liberties without sacrificing security. Because of the rapidity with which the law was enacted, Congress, wisely, included a four-year sunset of many of the provisions of the new Act. That sunset will allow Congress to make some needed adjustments, hopefully in a calmer climate, and strengthen the protections for civil liberties without sacrificing security.
Section 216
The Patriot Act substantially changes the law with respect to law enforcement access to information about computer use including Web surfing. Reaching for an analogy from the old rotary dialed telephone system, the Act extends provisions written to authorize installation of pen registers and trap and trace devices, which record outgoing and incoming phone numbers, to authorize the installation of devices to record all computer routing, addressing, and signaling information. The government can get this information with a mere certification that the information likely to be obtained is relevant to an ongoing criminal investigation.
