The American Civil Liberties Union and the Center for National Security Studies filed three Freedom of Information Act requests Jan. 22 seeking the immediate release of records related to President Bush's authority to search Americans' mail without a warrant. The president claimed this authority in a Dec. 20 signing statement that accompanied the Postal Accountability and Enhancement Act of 2006. The ACLU, CNSS and other groups maintain the act does not change the current protections, which under the Foreign Intelligence Surveillance Act of 1978 and federal criminal rules require judicial approval before domestic sealed mail can be searched. Postal inspectors may search a sealed package or envelope when there is immediate danger to life or immediate and substantial danger to property. This occurs, for example, when wires protruding from a package, odors escaping from an envelope or stains on a package indicate the contents may constitute such a danger. The ACLU and CNSS
