Wow, that was pretty cool. The scary part, is that it could actually be happening in some markets. New car, bank loans, credit cards, insurance... I've got a hunch there is way too much information availiable. You can access the local court house, type in a name, get back court dates, trafic tickets, property they own, addresses lots of stuff. Your credit report contains lots of stuff you would think was anybodies business (second notice on your power or phone bill).
I don't think it too paranoid to believe there search engines and databases, that aren't availiable to the average Joe Surfer. Wonder if our ISP record ever website we visit. The small town I live in, is installing city wide wireless internet, and offering free access. At first, I could see how the police would benefit, maybe a few other services. But they dumped millions into this, and got to figure there is some sort of catch.
