Bill Advances in France Giving Spy Agencies Vast Powers
The lower house of France’s Parliament overwhelmingly approved a sweeping intelligence bill that, if it wins in the upper house, would give the government broad surveillance powers with little judicial oversight.
The measure would give the intelligence services the right to gather potentially unlimited electronic data from Internet communications, and to tap cellphones and capture text messages. It would obligate Internet companies to comply with government requests to sift through subscribers’ communications.
