EFF: “Better late than never: last night a federal district court held that backdoor searches of databases full of Americans’ private communications collected under Section 702 ordinarily require a warrant. The landmark ruling comes in a criminal case, United States v. Hasbajrami, after more than a decade of litigation, and over four years since the Second Circuit Court of Appeals found that backdoor searches constitute “separate Fourth Amendment events” and directed the district court to determine a warrant was required. Now, that has been officially decreed. In the intervening years, Congress has reauthorized Section 702 multiple times, each time ignoring overwhelming evidence that the FBI and the intelligence community abuse their access to databases of warrantlessly collected messages and other data. The Foreign Intelligence Surveillance Court (FISC), which Congress assigned with the primary role of judicial oversight of Section 702, has also repeatedly dismissed arguments that the backdoor searches violate the Fourth Amendment, giving the intelligence community endless do-overs despite its repeated transgressions of even lax safeguards on these searches. This decision sheds light on the government’s liberal use of what is essential a “finders keepers” rule regarding your communication data. As a legal authority, FISA Section 702 allows the intelligence community to collect a massive amount of communications data from overseas in the name of “national security.” But, in cases where one side of that conversation is a person on US soil, that data is still collected and retained in large databases searchable by federal law enforcement. Because the US-side of these communications is already collected and just sitting there, the government has claimed that law enforcement agencies do not need a warrant to sift through them. EFF argued for over a decade that this is unconstitutional, and now a federal court agrees with us…”
