It's not ISP wide - it's person specific (Score 1)

The c_vore system is using a person's identity to key against raw internet traffic. As mentioned, this is not an echelon type system where they look for keywords that are likely to provide information regarding crimes or terrorism. This kind of filtering can only be done when there are foreigners involved anyway. Americans, at least for now, are protected by some pretty good oversight. They go to the ISP where that individual has an account and start from there? Wow, that sounds pretty good to me. It's alot better than them trying to filter all content all over the internet (impossible). I think this time the government is actually doing it right. Going to the ISP where the person's email account is at even further reduces the likelyhood that the will inadvertantly intercept your email. They use this less than 100 times a year? Wait... How many ISPs are there? Which one does the criminal or suspected criminal use? Is it the same as your ISP? Did you email the criminal? Why did you email the criminal? Don't be the criminal... don't email the criminal. Wait until your good buddy the ciminal is in the clear. If you commit a crime are suspected of it, your privacy will be violated. I guarantee it. Whether you know about it or not and no matter what technology you use. If you are falsely accused it's a real bummer. Just happened to me recently.
