The real way to make us safe and secure is to ensure nobody gets on a plane with credible weapons or explosive devices. That's what the TSA is supposed to be doing, instead of all their mission creep, ID fixation and other make-work activities.

We are safer than before (9/11 I assume) because:
a) flight decks are less accessible to passengers (again supposedly); and
b) crews and passengers have learned (hopefully) that co-operating with terrorists does no good at all so you may as well resist/atttack.
