Bruce Schneier on fallout from Paris attacks:
"Terrorism is singularly designed to push our fear buttons in ways completely out of proportion to the actual threat.

This means that those who want those powers need a steady stream of terrorist attacks to enact their agenda. It's not that these people are actively rooting for the terrorists, but they know a good opportunity when they see it...."
