Believe with the advent of TSA the FAA is mostly out of the "retail" passenger security business. And a good job too.
Now if everybody would also understand that the FAA has nothing directly to do with the commercial aspects of airline operations (frequent flyer programs, fares, schedules, permission to operate from Armpit to Lower Slobovia, cabotage (whatever that is), fifth freedom (and freedom's 1 through 4 too), the coffee too hot/too cold, pax seats too close together, etc would be a lot easier.
All concerned should understand that even when FAA had security responsibility it was limited by the Congress and the "input" of stakeholders in industry and other places in what it was allowed to do. And if it made things too tight, or even talked about it, rightous indignation, rockets (metaphorical) and direction followed from higher level management. Where were they 9/11?
Because FAA "didn't do it's job" (never mind wasn't allowed to) TSA will now take over and everything will be grand. Direction from upper level management since 9/11 on absolute enforcement of the letter of the regulations (b*&^%&* common sense) came from law enforcement and national security by edict. Now you have a TSA staffed by very few people who know the pointy end from the blunt end of an airplane or how aviation runs, so good luck. It will cost the earth for, I think, a modest increase in security and keep the "me too" and not so tightly wrapped terrorists (the majority) at bay, but the real sophisticated operators are already on to different ways of getting into the airport or airplane or to other means of producing terror anyway.
