Which law aims to enhance national security after September 11, 2001?

The USA PATRIOT Act was established to enhance national security in response to the events of September 11, 2001. Its primary goal is to provide law enforcement agencies with the necessary tools and authority to combat terrorism more effectively. This includes provisions for increased surveillance capabilities, enhanced investigative powers, and improved information sharing between government agencies.

The act reflects a shift in priorities where security measures were vastly expanded and adjusted to address the new threats posed by terrorism. It outlines how law enforcement can monitor telecommunications, gather intelligence from various sources, and deport foreign nationals suspected of terrorist activities, all in an effort to protect national interests and ensure public safety.

While other laws mentioned may relate to security or defense, they do not specifically address the immediate need for enhanced national security in the aftermath of the September 11 attacks, as the USA PATRIOT Act does. For instance, the Homeland Security Act established the Department of Homeland Security but did not focus solely on the immediate legal measures to combat terrorism. The National Defense Authorization Act pertains to budgetary and policy provisions for the military, while the Safe Streets Act focuses more on crime prevention rather than national security in the context of terrorism.
