While activists and politicians work to repeal or change parts of the Patriot Act that they say violate constitutional rights, Patriot Act II legislation -- which caused a stir when it came to light last year -- is rearing its head again in a new bill making its way through Congress.

"If the government is able to conduct its powers in secret, then we never know the extent to which its power is being used or being abused," he said. "If the government wants to conduct more of its business in secret and without probable cause, then (we should) just amend or repeal the Fourth Amendment, not allow the government to eat away at it in small steps and pretend it's still there."

Barr said the law should allow recipients of national security letters the right to challenge them, just as they can challenge grand jury subpoenas.

The American Civil Liberties Union recently discovered just how daunting the secrecy provisions can be when it was forced to file a lawsuit in secret that challenged the constitutionality of national security letters under the First Amendment. The organization was able to reveal the existence of the lawsuit only after negotiating with the government about what it could say about the suit.

The lawsuit was filed after the ACLU filed a Freedom of Information Act request for information about how often and in what cases authorities have used national security letters to date, and the organization received six pages of blacked-out documents.

"The last time (a Patriot Act II provision) slipped through and got signed was on the day of Saddam Hussein's capture," Pitts said. "There was not a single activist who knew it was coming down the pike. At least this time we know about it in advance."
