For those on the list who were unenthusiastic about profiling - things may get worse. The Washington Post is reporting that the government and the airlines are developing a vast air security screening system designed to instantly pull together every passenger's travel history and living arrangements, plus a wealth of other personal and demographic information. Delta and Northwest Airlines have acknowledged that they are talking with other airlines about a similar screening system. Joseph Del Balzo, a former acting administrator of the Federal Aviation Administration and a security consultant working on one of the profiling projects was quoted as saying "...is based on transaction analysis, behavior analysis, gives us a pretty good idea of what's going on in a person's mind." A penny for your thoughts? The American Civil Liberties Union had a few quotes of their own: "It really is a profound step for the government to be conducting background checks on a large percentage of Americans."
