Spying on all will not make us safer
Einstein says that to repeat an action in the hope of a different outcome is insane. After 9/11 we reacted by bombing the Middle East and attacking our own liberties. After Paris, there are calls to repeat this response. Why do we expect a different outcome this time?
The faint-hearted are calling for the snooper's charter. France has a snooper's charter. Will we copy them? Spying on everybody dilutes our intelligence and allows criminals and terrorists to sneak through in the crowd.
The answer is targeted surveillance, not blanket snooping. France tried blanket snooping and look where it's got them.
