The USA PATRIOT ACT [1] (Public Law 107-56) is short for "Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism" Act of 2001 and is a controversial piece of federal legislation in the United States.
Passed after the September 11, 2001 attacks, the Act was formed in response to the terrorist attacks against the U.S., and dramatically expands the authority of U.S. law enforcement for the stated purpose of fighting terrorist acts in the United States and abroad. It is also used to detect and prosecute other alleged potential crimes such as providing false information on terrorism. It was renewed on March 2, 2006 with a vote of 89–11 in the Senate and on March 7 280–138 in the House. The renewal was signed into law by President George W Bush on March 9, 2006.
