Roving wiretap

In United States law, a roving wiretap is a wiretap that follows the surveillance target. For instance, if a target attempts to defeat surveillance by throwing away a phone and acquiring a new one, by moving, or by any other methods, another surveillance order would usually need to be applied for. However, a "roving" wiretap follows the target, and defeats the target's attempts at breaking the surveillance by changing location or their communications technology. In the US, it is allowed under amendments made to Title III of the Omnibus Crime Control and Safe Streets Act of 1968 (the "Wiretap Statute") in 1988 by the Electronic Communications Privacy Act, and was later expanded by section 604 of the Intelligence Authorization Act for Fiscal Year 1999.
