When we have some horrible terrorist attacks happen in some country we see in the recording that follows, that the intelligence community already knew about these people in advance. We know that these countries were involved in intelligence sharing premiums, that they benefited from mass surveillance, and yet they didn't stop the attacks. Yet at the same time we immediately see intelligence officials running to the newspapers and claiming that we need more surveillance, that we need more intrusion, that we need more expense of powers because it could have stopped an attack.
