The sad truth is that for a while air travellers will be subjected to ridiculously long delays until those in charge grow complacent - again - and those watching and waiting for an opportunity take advantage.
Sooner or later they are going to recruit more efficient suicide bombers for the job.

There is no excuse for all these blatant signs of a real problem to have been ignored or allowed to "slip through the cracks". Two hundred plus lives in addition to those killed on the ground nevermind the effect on national morale is a very big crack.
