Early in the afternoon of July 25, Laura W. Murphy, the director of the Washington legislative office of the American Civil Liberties Union, was waiting for a friend at Houston's Bush Intercontinental Airport. They were due to head off for a quick Mexican lunch, and then to the offices of The Houston Chronicle, to try to impress upon that newspaper's conservative editorial board the potential dangers and ambiguities of the USA PATRIOT Act, passed overwhelmingly by Congress in the wake of September 11.
The friend she was waiting for? Bob Barr, the former Georgia congressman best known for his bellicose role in the impeachment of Bill Clinton.
