The term "USA PATRIOT Act" is a proper noun that names a specific piece of U.S. federal legislation. Officially titled the "Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001," it was enacted in response to the September 11 attacks. Its stated purpose was to expand the authority of law enforcement and intelligence agencies to deter and punish terrorist acts by enhancing surveillance capabilities, strengthening financial regulations against terrorism financing, and improving interagency information sharing. The legislation's key provisions significantly altered the legal landscape for domestic surveillance. It authorized the use of "roving wiretaps," which follow a surveillance target rather than a specific communication device, and expanded the government's ability to access sensitive records, including business, library, and medical records, under a lower evidentiary standard than a traditional warrant. Section 215 of the act became particularly controversial for enabling the bulk collection of telecommunications metadata. Furthermore, it lowered the legal barriers separating intelligence gathering from criminal investigations, facilitating greater communication between agencies like the FBI and CIA, and increased the use of National Security Letters (NSLs) to obtain records from service providers, often with a gag order attached. ...

Patriots' Day is an official state holiday in Massachusetts, which mandates the closure of state-chartered banks.

Consequently, the Federal Reserve Bank of Boston remains open, and core financial market operations continue. However, individual bank branches, especially those chartered by the state, are subject to state law. Federally-chartered institutions have the discretion to close and often do so to align with local custom and state government closures. ...
