The war on terror has been about scaring people, not protecting them
The ease with which the plane bomber could operate exposes the vacuity and recklessness at the heart of the US response to 9/11. So there was no ticking time bomb. No urgent need ever arose to torture anybody who was withholding crucial details, so that civilisation as we know it could be saved in the nick of time. No wires had to be tapped, special prisons erected or international accords violated. No innocent people had to be grabbed off the street in their home country, transported across the globe and waterboarded. Drones, daisy-cutters, invasions, occupations were, it has transpired, not necessary.
