The fourth admendment covers it. It is just up to the powers that be to enforce it.

And Bronco:

1) Of course no one knows who was effected, that is why there is no national security risk like the President claims, unless having public acknowledgement that we will adhere to our own constitution is a security risk. That is all that was disclosed. No investigations were compromised because no specific details were disclosed

2) Yea, yea, the old mushroom cloud scare tactic. Having civil liberties is a risk. Law enforcement would be much easier without them. No one denies that. It is just that real American patriots view freedom and civil liberties as greater than destroying our rights because you are cowering in fear from a few terrorist nutjobs.
