The Paris prosecutor's office said on Wednesday it had launched a preliminary investigation into the U.S. National Security Agency's Prism surveillance program after French rights groups complained it was snooping on citizens' emails and phone calls...The groups filed their complaint against "persons unknown" but named Microsoft, Yahoo, Google, Paltalk [part of AVM Software], Facebook, AOL and Apple as "potential accomplices" of the NSA and FBI. The original complaint was filed by the International Federation for Human Rights (FIDH) and the French Human Rights League (LDH)...The prosecutor's office said it had ordered investigating police to examine claims of fraudulent access to an automated data processing system, collection of personal data by fraudulent means and willful violation of the intimacy of private life.
