Case Studies: No Data

As part of the Homeland Security Act of 2002, Public Law 107-296, Congress enacted several levels of liability protection for providers of anti-terrorism technologies. The SAFETY Act (the Act) provides incentives for the development and deployment of anti-terrorism technologies by creating a system of risk management and a system of litigation management.
