to gather "foreign intelligence information" from both U.S. and non-U.S. citizens, and changed FISA to make gaining foreign intelligence information the significant purpose of FISA-based surveillance, where previously it had been the primary purpose. The change in definition was meant to remove a legal "wall" between criminal investigations and surveillance for the purposes of gathering foreign intelligence, which hampered investigations when criminal and foreign surveillance overlapped. However, that this wall even existed was found by the Federal Surveillance Court of Review to have actually been a long-held misinterpretation by government agencies. Also removed was the statutory requirement that the government prove a surveillance target under FISA is a non-U.S. citizen and agent of a foreign power, though it did require that any investigations must not be undertaken on citizens who are carrying out activities protected by the First Amendment. The title also expanded the duration of FISA physical search and surveillance orders, and gave authorities the ability to share information gathered before a federal grand jury with other agencies. The scope and availability of wiretapping and surveillance orders were expanded under Title II. Wiretaps were expanded to include addressing and routing information to allow surveillance of packet switched networks—the Electronic Privacy Information Center (EPIC) objected to this, arguing that it does not take into account email or web addresses, which often contain content in the address information. The Act allowed any district court judge in the United States to issue such surveillance orders and search warrants for terrorism investigations. Search warrants were also expanded, with the Act amending Title III of the Stored Communications Access Act to allow the FBI to gain access to stored voicemail through a search warrant, rather than through the more stringent wiretap laws. Various provisions allowed for the disclosure of electronic communications to law enforcement agencies. Those who operate or own a "protected computer" can give permission for authorities to intercept communications carried out on the machine, thus bypassing the requirements of the Wiretap statute. The definition of a "protected computer" is defined in and broadly encompasses those computers used in interstate or foreign commerce or communication, including ones located outside the United States. The law governing obligatory and voluntary disclosure of customer communications by cable companies was altered to allow agencies to demand such communications under U.S.C.
