Some local citizens have recently voiced the opinion that people opposed to drug testing must obviously have something to hide. In the bicentennial year of the Constitution, this attitude demonstrates not only an appalling lack of knowledge concerning the basic foundation of our government, but also a profound misunderstanding of the issues surrounding the newly required drug testing of Fairfax County schoolbus drivers.

As a Fairfax County schoolbus driver, I believe that the real issue here is whether such drug testing, without any demonstrated or even probable cause, is an invasion of privacy, which violates the rights and privileges guaranteed to the people in the 4th Amendment to the Constitution. Using the "nothing to hide" logic, it could easily be construed that the government has the right, without probable cause and the possession of a search warrant, to enter our homes or conduct public strip searches.

Although drug abuse is an acknowledged social problem and the innocent may truly have nothing to hide, to allow such unbridled behavior on the part of government would cost us too dearly of our human dignity. In fact, it would violate the very concepts central to a civilized society.

With such wanton drug testing in place, our own George Mason would be appalled, and Joe McCarthy would feel right at home.
