9/11 was planned as an excuse to implement the new airport security system. The full body scanners was a scheme they hope to hatch long before they were rolled out (see the movie Total Recall). 9/11 was the catalyst for implementing the over-reaching and necessary SURVEILLANCE system. The reason for the body scanners has little to nothing to do with promoting safety aboard airliners it is a way to create a 'universal catalog' of names, faces, bodies they are creating a identity matching system. Those scanners are capable of reading DNA level information and blood type. They are souped up MRI systems. They are BUILDING A CATOLOG. The term in the intel community for what they are doing is MASINT
They have been doing voice printing for ages via THE TELEPHONE SYSTEM. "random calls" out of nowhere are a way of voice printing you. You say "Hello" --done..gotcha. The scanner machines the TSA are using are "body printing'. The technology for doing blood typing and DNA is very much available. Ever wonder why they used cameras with multiple lenses at the DMV?
The same technology that you use to identify songs by holding your smartphone up to the speaker at a bar is the same technology used to identify airplanes and submarines and yachts by the sounds their engines make, etc. The same technology is now being turned against "the populace". It is conceivably possible to reconstruct a hard drive or a SSD device based on detailed MRI-type scans. THEY ARE BUILDING A CATALOG OF EVERYONE THAT PASSES THROUGH. By having a super HD 3d catalog (at the molecular level) they can identify someone from the side even if it just means narrowing down who it might
If you question the above, look at how CERN, Fermilab, etc. use x-rays and gamma rays generated by particle accelerators to study molecular and molecular structures.
So what is mandatory? It is mandatory
for TSA to continue building the catalog.
