Hypocrisy is on show in a Manhattan courtroom today. The New York Civil Liberties Union will argue for the second day before Judge Richard Berman that the city's subway bag search policy is an "unjustifiable erosion of the privacy rights of the American public." Yet take a walk into the NYCLU's Manhattan headquarters - which it shares with other organizations - and you'll find a sign warning visitors that all bags are subject to search. One of the city's lawyers, Jay Kranis, pointed this out yesterday in court while cross-examining a witness. Either the NYCLU believes its headquarters are at greater risk of a terrorist threat than the city's subway system, or it believes ordinary New Yorkers don't deserve the same safety precautions that they do.
