This report discusses commercial ties between the United States and the 27-member European Union.

This report is intended to serve as an introduction and primer on this complicated, broad, and often highly technical set of issues.

This report is a comparison of the laws of the United Kingdom and of the United States that govern criminal and intelligence investigations of terrorist activities. Both systems rely upon a series of statutory authorizations: in the case of the United States primarily the Foreign Intelligence Surveillance Act and the Electronic Communications Privacy Act; in the case of the United Kingdom, the Regulation of Investigatory Powers Act, the Police Act, the Intelligence Services Act. Among other differences, the U.S. procedures rely more heavily upon judicial involvement and supervision, while those of the UK employ other safeguards. The UK procedures afford greater latitude to arrest, detain and supervise suspected terrorists than those available in the United States.
