She became ill at home and a doctor diagnosed : her condition as "water intoxication." The lack of privacy inhibits : 25 percent of people from urinating, surveys show [JAMA 1/2/91]. Drug testing doesn't even work. Could there be a more important use for it than public safety? It made no difference to the drunk and sleepy subway motorman in the spectacular underground smash-up at the Union Square Station in NYC. Even if he had a drug test before his shift, he still would have had the accident. Non-invasive (eye-hand co-ordination and other) tests would work better and not shockingly subject us to highly intrusive poking. It also doesn't work inasmuch as it has had no affect whatsoever on drugs. * Main Justice, by Jim McGee and Brian Duffy, 1996, ISBN 0-684-81135-9 * * The drug war never had a stronger supporter than President George Bush. * * He showered the nation's drug warriors with money---nearly tripling the * overall anti-narcotics budget from $4.3 billion in 1988 to $11.9 billion * in 1992. * * The results were disappointing. * * After four years there was more cocaine on the streets than ever. * Naturally, it was also cheaper than ever. * * The overall crime rate was unchanged too. * * Inside Main Justice, such n

July 1997 # # Currently housed at the National Security Agency, a working group of # federal bureaucrats founded the Biometric Consortium in the early 1990s. # Its 1995 charter promises to "promote the science and performance of # biometrics for the government." # # Consortium mumbers include state welfare agencies, driver's license # bureaus, the Immigration and Naturalization Service, the Social Security # Administration, and the Internal Revenue Service. If my attempts to show how bad a thing this is have been too rambling, too abstract, here is a simple and accurate analogy: * "Project L.U.C.I.D.", by Texe Marrs, 1996, ISBN 1-884302-02-5 * * It was Martin Anderson who, in his book, Revolution, revealed that during * the Reagan administration during the 1980s, several top cabinet officials * were urging President Ronald Reagan to implement a computerized National * I.D.

[Reagan had been Governor of California] * * But Anderson, who at the time was a domestic advisor to the President and * sat in on this particular cabinet meeting, spoke up and gave the group * something to think about. * * "I would like to suggest another way that I think is a lot better," he * told them, serious in demeanor but clearly being facetious. "It's a lot * cheaper, it can't be counterfeited. It's very lightweight, and it's * impossible to lose. It's even waterproof." * * "All we have to do," Anderson continued, "is tattoo an identification * number on the inside of everybody's arm." * * His reference was to the tattooing of numbers on victims in Nazi * concentration camps.
