TL;DR, mais la citation donnée par Laurent Chemla :
« We know in the Charlie Hebdo attack, in the attack in Canada, in the attack in Australia, all these individuals were known to government in advance of the attacks. It was not the fact that we were not watching people enough but the fact we were watching people so much we did not understand what we had. »
