Okay - there has to be some line to the level of security that goes for airport employees. If done correctly, you would not believe the time and research that goes into "clearing" a person to work at the airport. Each airline and/or vendor has to drug test, fingerprint (both w/the USPS and FBI), 10 year background check (includes calling and verifying employment), 10 year address check, driver's license check, and about 900 other pages of documentation. Then, IF the airline hires you after all of that...you go through the airport's security clearance on top of that. And now we should screen these people on their way to work? So, who screens the employees? And who screens the screeners? Who makes sure the airport police officers are good guys vs. bad guys? There comes a point when we're running in circles and focusing our energy on the wrong people. And yes...I also know that you cannot stop every threat, but how many times have you heard about aircraft being hijacked and crashed by airline employees? Amazingly enough, as stressful as things seem to be for those people, I've never heard of an airline employee going "postal".
