Why was the US patriot ac passed?

The USA PATRIOT Act was passed in response to the September 11, 2001 terrorist attacks. Its primary aim was to enhance national security by providing law enforcement agencies with expanded surveillance and investigative powers to prevent future attacks. The Act also aimed to improve inter-agency collaboration and share intelligence related to terrorism. Critics argue it infringes on civil liberties, but proponents contend it is essential for protecting the nation.
