PATRIOT Sunsets Extension Act of 2011 allows for roving wiretaps similar to the ECPA, effectively enabling spies to intercept a suspect’s electronic and wire communications associated to suspect conduct under the PATRIOT Act 2000, regardless of their location. This helps track suspects who move from phone booth, handset or computer to computer multiple times in order to foil tacking efforts. Roving wiretapping necessitates interception of email communications (without naming the communications carrier and other third parties involved in the tap). Section 209 allows stored voice mail to be treated as data as defined under section 2703 as against intercepts ...
