All the crap the airlines pulled after 9-11:
Breaking off nail files: Did this really make anyone safer? What happens if the terrorists send 10 300 pound karate experts?
Strip searching your grandma: After all the stories I've heard from people that have flown post 9-11 of old women and 80 year old congressional medal of honor winners getting searched, I firmly believe the airlines have a secret policy of picking on people who are completely unlikely to be terrorists, simply to prevent lawsuits for "racial-profiling." Yet with all this "security, a woman got on a plane with a gun in her carry-on(she got caught on the second leg of her her flight).
The only thing that made the airlines safer after 9-11 was the passengers. It was the passengers that prevented Richard Reid (the shoe-bomber) from blowing up the plane, and it is the passengers that subdue everybody that gets even a little whacky on a flight these days. All the airlines are interested in doing is providing an illusion of security, so they can continue to rip you off as a consumer and as a taxpayer. Remember the bailouts, and the layoffs, while the CEOs still make huge bucks? Remember the security screeners that were coached through federal exams?
The most shocking thing I've read after 9-11 is that several of the hijacked passengers who called their loved ones on their cell phones said the hijackers had guns. Yet this has never been officially confirmed. Why? Because it illustrates a huge security failure, and publicizing it would be bad for business. Instead they search your grandma.
