A new rush to spy

There is apparently no limit to the Bush administration’s desire to invade Americans’ privacy in the name of national security. According to members of Congress, Attorney General Michael Mukasey is preparing to give the F.B.I. broad new authority to investigate Americans — without any clear basis for suspicion that they are committing a crime.

Opening the door to sweeping investigations of this kind would be an invitation to the government to spy on people based on their race, religion or political activities.
