The FAA's policies are getting completely out of hand. There has been no proof that restricting liquids and full body scanners have actually stopped any terrorist attack. It is just a way to make the consumers feel more safe when they travel, and to inflict fear into passengers travelling at the time.
Everybody knows that the rules for what you can and cannot carry onto a plane are totally worthless. But we all pretend that stopping grandma from carrying on her full-size shampoo bottle is helping STOP TERRORISM, so we allow the farce to continue. Americans need to stand up and demand that the FAA and other related agencies stop the security theater policies that don't make us any safer.
The FFA still will not allow liquids to be brought in carry-one and yet they pack people in like sardines for hours at a time without food or water. It is inhumane to say the very least. It is a very explorative business practice and it seems like the purpose is to increase profits not safety.
TSA says the scanners add another layer of security at checkpoints besides metal detectors, explosives-detection systems and bomb-sniffing dogs. For example, a ceramic knife might not trip a metal detector and might not have an explosive scent for a dog to detect.
The threats the machines could have detected include the shoe bomb Richard Reid attempted to detonate on an international flight to the U.S. in December 2001, Umar Farouk Abdulmutallab's underwear bomb on an international flight in December 2009 and two non-metallic explosives in Yemen printer cartridges in October 2010.
The full-body scanners used in all airports since May 2013 are called "millimeter wave" machines, which bounce electromagnetic waves off the traveler to provide an animated image where a suspicious item might be located. The TSA no longer uses the backscatter scanners that produced near-naked images of travelers.
Many of the FAA's policies are inconvenient and bothersome, but they were originated for a reason. Even the impractical policies have a purpose. The regulations are analyzed, evaluated and changed as needed on an ongoing basis. The primary role of the FAA and its policies is to protect the general public.
