"Taken together, those activities raise unique privacy and oversight concerns greater than those posed by large-scale monitoring of voice communications. ... If the reports are correct, what this transactional-data-dragnet amounts to is a rebuilding of the Defense Department [4]'s Total Information Awareness [5] program, which promised to do extensive warrantless data-mining to identify 'information signatures' that could identify criminals."
