> When the US government decides a US citizen's communication patterns makes him a terrorist, the US government is free to knock down their door in the middle of the night and whisk them off to Guantanamo, and NO ONE except the US government can do anything to stop them.

While I dislike how the U. S. government has decided that who they classify as terrorists superceding the rights of a US citizen, this is just wrong. Communicating with terrorists on a typical basis isn't enough for the U. S. government to do so - the only cases where I have heard of this happening is when the US citizen in question has carried out actual violent terrorist actions such as armed combat.

You have far less protection against the U. S. government if you are not a citizen, since there is nothing protecting you against broad actions. You can be assassinated in the middle of the night & your government wouldn't be able to do a damn thing to pre-empt that. There are also far less protections as to spying as well, but that has nothing to do with this article.
