In Friday's ruling, the court said computer users should know that they lose privacy protections with e-mail and Web site addresses when they are communicated to the company whose equipment carries the messages.

The ruling "further erodes our privacy," the attorney said. "The great political marketplace of ideas is the Internet, and the government has unbridled access to it."

The court case is a bit bogus, the guy was manufacturing Ecstasy, which I'm sure didn't help. Ingoring that detail, it is quite scary what the courts just said was allowable. They can watch where you go on the internet. The whole idea of 'they can't see what you are looking at' is bs. Any user can look at a URL visited and type it in themself to see what is there. The compare it to looking at the outside of a package. I can't just get another identical package and open it though, with the internet that is the case. So much data is also passed through the URL bar (anything with ?function=value after it is passing data (look at your google search page. Notice the q=proxyhost.com. Is it REALLY not invading my privacy? Remember the AOL case where the leaked millions of searches and people could be identified and their privacy was violated?

The right of the people to be secure in their persons, houses, papers, and effects, against unreasonable searches and seizures, shall not be violated, and no warrants shall issue, but upon probable cause, supported by oath or affirmation, and particularly describing the place to be searched, and the persons or things to be seized. - Bill of Rights

I see the court felt differently, but I certainly think it is unreasonable searching of what I am doing if the government can monitor all my internet activity without so much as a warrant.
