Homeland Security revives supersnoop

I Have no opinion on this until I can learn more...

From The Washington Times:

Homeland Security officials are testing a supersnoop computer system that sifts through personal information on U.S. citizens to detect possible terrorist attacks, prompting concerns from lawmakers who have called for investigations.
The system uses the same data-mining process that was developed by the Pentagon's Total Information Awareness (TIA) project that was banned by Congress in 2003 because of vast privacy violations.
A Government Accountability Office (GAO) investigation of the project called ADVISE -- Analysis, Dissemination, Visualization, Insight and Semantic Enhancement -- was requested by Rep. David R. Obey, Wisconsin Democrat and chairman of the House Appropriations Committee.
The investigation focuses on whether the program violates privacy laws, and the findings will be released after completion of the Iraq war supplemental spending bill, possibly as early as this week, a panel aide said.
The ADVISE and TIA data-mining projects rely on personal data to track individual behavior and consumer transactions to develop computer algorithms that create a pattern that some behavioral scientists say can predict terrorist behavior.
Data can include credit-card purchases, telephone or Internet details, medical records, travel and banking information.
Privacy concerns prompted lawmakers on both sides of the aisle to introduce legislation in January to require that government agencies disclose data-mining practices in regular reports to Congress.

It sounds scary for sure, but i just need to know more about it and how the information is handled or stored before condemning it, or approving of it.
