Airport security should be about securing airtravel, not securing the collective asses of TSA or whatever lump of agencies and companies it is these days. And IMHO, even airtravel doesn't need that much securing. And the collective ass needs even less. Sealed cockpit doors are definitely a good measure for the decades old hijacking problem and the newer, though much more unlikely, 9/11 copycat situations. Other than that, the passengers can't really do much on a plane.
