As a worker in that field, I stongly, strongly disagree. Security matters are not for discussion in public discourse. End of.
I'll discuss whatever I want, when I want. End of.
Until I am treated as part of the solution and not part of the problem, I'll be a little more gracious. But until then, I have greater chance (probably by several orders of magnitude) of losing my job because I haven't followed some stupid rule than by any terrorist action. The muppets guarding the magnetic arches are making the lives of the travelling public and operating crews more difficult purely for (expensive) window dressing reasons. Unfortunately, "Security" confuses action with achievement.
