What Right Does The Military Have To Spy Upon American Citizens?

There are a wealth of stories in The New York Times over the weekend which makes me ask the question posed in this post's headline, "What right does the military have to spy upon us?", including this one:

Deep into an updated Army manual, the deletion of 10 words has left some national security experts wondering whether government lawyers are again asserting the executive branch’s right to wiretap Americans without a court warrant.

The manual, described by the Army as a “major revision” to intelligence-gathering guidelines, addresses policies and procedures for wiretapping Americans, among other issues.

The original guidelines, from 1984, said the Army could seek to wiretap people inside the United States on an emergency basis by going to the secret court set up by the Foreign Intelligence Surveillance Act, known as FISA, or by obtaining certification from the attorney general “issued under the authority of section 102(a) of the Act.”

That last phrase is missing from the latest manual, which says simply that the Army can seek emergency wiretapping authority pursuant to an order issued by the FISA court “or upon attorney general authorization.” It makes no mention of the attorney general doing so under FISA.

Bush administration officials said that the wording change was insignificant, adding that the Army would follow FISA requirements if it sought to wiretap an American.

But the manual’s language worries some national security experts. “The administration does not get to make up its own rules,” said Steven Aftergood, who runs a project on government secrecy for the Federation of American Scientists.

There is also this in the Times, titled, "Military Expands Intelligence Role In The U.S." as if what we really desperately need is Bush's personal KGB:

The Pentagon has been using a little-known power to obtain banking and credit records of hundreds of Americans and others suspected of terrorism or espionage inside the United States, part of an aggressive expansion by the military into domestic intelligence gathering.

The C.I.A. has also been issuing what are known as national security letters to gain access to financial records from American companies, though it has done so only rarely, intelligence officials say.

Banks, credit card companies and other financial institutions receiving the letters usually have turned over documents voluntarily, allowing investigators to examine the financial assets and transactions of American military personnel and civilians, officials say.

The F.B.I., the lead agency on domestic counterterrorism and espionage, has issued thousands of national security letters since the attacks of Sept. 11, 2001, provoking criticism and court challenges from civil liberties advocates who see them as unjustified intrusions into Americans’ private lives.

But it was not previously known, even to some senior counterterrorism officials, that the Pentagon and the Central Intelligence Agency have been using their own “noncompulsory” versions of the letters. Congress has rejected several attempts by the two agencies since 2001 for authority to issue mandatory letters, in part because of concerns about the dangers of expanding their role in domestic spying.
