Which law, passed in 2002, aimed to improve security and prevent terrorism after 9/11?

The USA PATRIOT Act, enacted after the September 11 attacks in 2001, was designed to enhance the government's ability to prevent terrorism and improve national security. This law expanded the surveillance capabilities of law enforcement agencies, allowing them to monitor communications and access personal records more freely.

The significance of the USA PATRIOT Act lies in its immediate response to the terrorist attacks and the urgent need for heightened security measures. This reflects a critical moment in U.S. history where civil liberties and national security concerns began to clash, shaping the national dialogue in the years that followed.
