Couldn't care less what the ACLU claims if they're your star-witness your case is in serious trouble.
Haven't you said before that Wikipedia isn't a good source when it comes to contraversial issues.
Here is a source to sit down and read but it is only talking hypotheticals, not giving instances of abuse.
Uh if you look at the source's title it sounds more like a left-wing blog site than a University.
Okay this article is kind of legit, but it missed the point, we're talking about two seperate issues, stiffling political opposition and trying to keep our sources of intelligence from being compromised.
