As the year comes to a close, Sens. Rand Paul, R-Ky., and Ron Wyden, D-Ore., two legislators on the opposite ends of the political spectrum, are sounding the alarm about the dangers of mass surveillance, especially in the digital age, in which much of our private information is on the Internet.

Last week, the two gave a joint talk at George Washington University about the implication of mass surveillance and the eroding of the Fourth Amendment due to the War on Terror. On Tuesday, they joined the American Civil Liberties Union, FreedomWorks, and other defenders of civil liberties such as Sens. Mike Lee, R-Utah, and Patrick Leahy, D-Vt., to specifically address Section 702 of the Foreign Intelligence Surveillance Act, which is set to expire at the end of this year.
