The Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism (USA PATRIOT) Act, P. L. 107-56, was part of the Congressional response to September 11.
According to a Congressional Research Service (CRS) "Report to Congress", the Act consists of ten titles which, among other things:
1) give federal law enforcement and intelligence officers greater authority (at least temporarily) to gather and share evidence particularly with respect to wire and electronic communications;
2) amend federal money laundering laws, particularly those involving overseas financial activities;
3) create new federal crimes, increase the penalties for existing federal crimes, and adjust existing federal criminal procedure, particularly with respect to acts of terrorism;
4) modify immigration law, increasing the ability of federal authorities to prevent foreign terrorists from entering the U.S., to detain foreign terrorist suspects, to deport foreign terrorists, and to mitigate the adverse immigration consequences for the foreign victims of September 11; and
5) authorize appropriations to enhance the capacity of immigration, law enforcement, and intelligence agencies to more effectively respond to the threats of terrorism.
These Titles are:
Title I - Enhancing Domestic Security Against Terrorism
Title II - Enhanced Surveillance Procedures
Title III - International Money Laundering Abatement and Anti-Terrorist Financing Act of 2001
Title IV - Protecting the Border
Title V - Removing Obstacles to Investigating Terrorism
