(NEWSER) – President Obama's proposed NSA reformsaren't nearly enough, says an independent federal agency that serves as a privacy watchdog. In fact, the Privacy and Civil Liberties Oversight Board thinks the NSA's surveillance is illegal and should be shut down, the New York Times reports. The board takes particular aim at the legal underpinnings of the surveillance, Section 215 of the Patriot Act. The government maintains that the law gives the NSA a green light to collect all phone records in the US, but the board disagrees. The law requires that such records be relevant to an investigation, and it's impossible that the billions obtained daily could be used for a single investigation "without redefining that word in a manner that is circular, unlimited in scope," concludes the report, per the Washington Post.
