The day after the attacks on Paris, much of the discussions on news programs was how this happened. Why didn't France or the US or Great Britain or anyone have listening devices centered on the Middle East to easedrop on wireless communications. NBC's Andrea Mitchell related that after the Edward Snowden business, warrants were required to go into encrypted internet conversations. And, most surprising to me Mitchell said that very likely the terrorists were using Sony Play stations to communicate wirelessly because these devices are encrypted.
Who knew. Play Stations of all things.
