The FBI’s deputy director, Paul Abbate, has said that Section 702 of the US Foreign Intelligence Surveillance Act is “absolutely critical for the FBI to continue protecting the American people”. The section permits targeted surveillance of communications belonging to people outside the US in order to prevent criminal and terrorist acts. However, it has previously been used to monitor US activists and journalists. The FBI, CIA and NSA can search collected communications without a warrant, and use them to prosecute individuals for crimes. Section 702 will expire at the end of 2017 unless it is renewed by Congress.
