With your life long law enforcement connections, you should be aware of the redox reaction used in the breathalyzer test to detect alcohol, correct? When it comes to profiling and distinguishing the air one exhales, things get a lot more complex.
As I mentioned earlier, this science has been around for over 45 years, it doesn't even represent cutting edge technology, and was used extensively by the "Stasi" East German secret police during the Cold War era. Even more revolutionary, intelligence services have now developed the ability to identify and track individuals by their heart beat, which is as unique to every individual as their fingerprints. Computerized facial recognition is also used extensively, and has been enhanced by satellite surveillance that is so advanced, operators can now read the small print on a paperback book page you are holding from space.
Through information mining, the federal government has complied tens of millions of profiles of subversives in America, which are stored in vast computer complexes like the NSA facility located just south of Salt Lake City, Utah. They know what stores you shop at, what products you buy, which ATM machines you use, and where you prefer to gas up your car. They can remotely record every key stroke of a personal computer, activate the camera of a personal computer and use it for surveillance, record text messages on a cell phones, ease drop on any phone communication in America without a warrant. They can also use cell phones to locate an individual within six feet of where they are standing, and can activate a cell phone and use it as a microphone, even when the phone appears to be inoperative.
I'll tell you something else most Americans are unaware of. Every major branch of the Federal Government, including the FBI, CIA, NSA, DOD and the Federal Marshall's Service, routinely employ an
army of psychics, who practice everything from psychometry (the ability to determine information about people and suspects by touching objects they've handled), to cold readings and psychic imaging. Why ? In simply terms, because it works.
