When Does the Government Need a FISA Warrant to Wiretap?
President Bush misled the public and Congress when he justified his administration's violations of the Foreign Intelligence Surveillance Act (FISA) by saying, "If Al-Qaeda is calling you, we want to know why!" According to current law, the government can already intercept most calls Al-Qaeda might make to U.S. residents without a warrant. This chart and the general rules below illustrate the mechanics of determining which call intercepts require warrants.
- If they are intercepting communications overseas, whether by targeting an individual or vacuuming up a stream of communications, they don't need a warrant, even if the overseas person is calling the U.S.
- If they are intercepting foreign to foreign communications, whether they intercept them in the U.S. or overseas, they don't need a warrant.
- If they are targeting people in the U.S., they generally need a warrant.
