U.S. Pressures ISPs on Data Retention
packetmon writes "According to Wired's Declan McCullagh 'In a private meeting with industry representatives, Gonzales, Mueller and other senior members of the Justice Department said Internet service providers should retain subscriber information and network data for two years ... A more extensive mandate would require companies to keep track of e-mail messages sent, Web pages visited and perhaps even instant-messaging correspondents.'"
Not to mention that all that extra has to be pored through. The FBI had gotten information on a case from homeland security, unfortunately they did not parse it down and the FBI agents lamented that they spent a majority of time chasing down pizza deliverys instead of spending more time on the actual case.
Image the uproar when (not if) a cracker gets into the database and abuses all that information.
The information gathered from users can also be used(abused) for blackmailing.
You might be asked to testify against someone, if not then well your employer and spouse might accidently find out about your surfing habits.
All in all, this sounds like a lose-lose situation for almost all involved.
