Remember the chorus of criticism of American surveillance practices by European politicians in the wake of the Snowden leaks?  No?  We don’t blame you.  Because after the Charlie Hebdo attacks, the pendulum has swung with lightning speed in the other direction, as politicians throughout Europe have called for more aggressive surveillance measures to fight terrorism.  Indeed, France already had such a measure in the works before the attacks, and it took effect January 1.  The new law permits an array of government agencies to obtain information on citizens’ electronic communications, including in real time, without judicial authorization.
