From the Summary: "The Foreign Intelligence Surveillance Act [FISA] Amendments Act of 2007 would make several modifications to the Foreign Intelligence Surveillance Act (FISA) and repeal several sections added to FISA by the Protect America Act of 2007 (Public Law 110-55). The bill would grant authority to the Attorney General and the Director of National Intelligence (DNI) to authorize surveillance of individuals or groups outside the United States. Such authorizations would permit the incidental acquisition of communications of individuals located within the United States so long as procedures are in place to minimize such acquisitions and to ensure that surveillance is targeted at individuals outside the United States. Under the bill, the Foreign Intelligence Surveillance Court (FISC) would be authorized to review those procedures and to order the government to modify them if the court finds they are inadequate or violate the Constitutional protections against unreasonable search and seizure. Section 101 of the bill would restrict the ability of the government to target U.S. persons located outside of the United States pursuant to authorizations by the Attorney General and DNI. Under the bill, if the government targets a U.S. person overseas but intends to acquire that individual's communications in the United States, the government must follow the traditional FISA warrant process for electronic surveillance."
