They Know Where You Are: IRS
The IRS is using records obtained from other federal agencies, state and local authorities, private organizations, and the media to compile profiles of individual taxpayers.
Every time you fill in any kind of form, a request for a bank loan, a cable-TV application, anything you put your S.S. number on you send personal information about yourself to the IRS.
Information about your credit history, what you eat, the type of car you drive is already contained in dozens of databases scattered throughout cyberspace.
