NSA warrantless wiretapping

NSA warrantless wiretapping refers to the U.S. National Security Agency's practice of monitoring phone and internet communications without obtaining individual warrants from a court. This program aimed to detect terrorist threats by collecting foreign-to-foreign communications, but was controversial because it raised concerns about privacy rights and the legality of spying without proper legal oversight. While initially justified by national security needs, the program sparked debate over balancing security and civil liberties, leading to increased calls for transparency, oversight, and legal safeguards.
