Subject: Carnivore Letter



Below is the text of the letter that the ACLU sent today to the House
Judiciary Subcommittee on the Constitution regarding the FBI's aptly
named "CARNIVORE" system for intercepting email. This is the system
that was the subject of this morning's story in the Wall Street Journal
and David Sobel's earlier posting.

Dear Representatives Canady and Watt:

We are writing to you about the new FBI email surveillance system aptly
named "Carnivore," which gives law enforcement extraordinary power to
intercept and analyze huge volumes of email. The Carnivore system gives
law enforcement email interception capabilities that were never
contemplated when Congress passed the Electronic Communications Privacy
Act  (ECPA), codified in relevant part at 18 U.S.C. 2510-22 and 18 USC
3121-27. Carnivore raises new legal issues that cry out for
Congressional attention if we are to preserve Fourth Amendment rights
in the digital age.

The existence of Carnivore first came to light in the April 6 testimony
of Attorney Robert Corn-Revere to the Constitution Subcommittee. Its
operation was further detailed in a report that appeared in today's
Wall Street Journal (copy attached).  According to these reports, the
Carnivore system -- essentially a computer running specialized
software-- is attached directly to an Internet Service Provider's (ISP)
network. Carnivore is attached either when law enforcement has a Title
III order from a court permitting it to intercept in real time the
contents of the electronic communications of a specific individual, or
a trap and trace or pen register order allowing to it obtain the
"numbers" related to communications from or to a specified target.

But unlike the operation of a traditional a pen register, trap and
trace device, or wiretap of a conventional phone line, Carnivore gives
the FBI access to all traffic over the ISP's network, not just the
communications to or from a particular target. Carnivore, which is
capable of analyzing millions of messages per second, purportedly
retains only the messages of the specified target, although this
process takes place without scrutiny of either the ISP or a court.

Carnivore permits access to the email of every customer of an ISP and
the email of every person who communicates with them. Carnivore is
roughly equivalent to a wiretap capable of accessing the contents of
the conversations of all of the phone companyÌs customers, with the
ÏassuranceÓ that the FBI will record only conversations of the
specified target.  This Ïtrust us, we are the Government" approach is
the antithesis of the procedures required under our the wiretapping
laws. They authorize limited electronic surveillance of the
communications of specified persons, usually conducted by means of
specified communications devices.  They place on the provider of the
communications medium the responsibility to separate the communications
of persons authorized to be intercepted from other communications.

Currently, law enforcement is required to ÏminimizeÓ its interception
of non-incriminating communications of a target of a wiretap order.
Carnivore is not a minimization tool. Instead, Carnivore maximizes law
enforcement access to the communications of non-targets.

In his testimony to your subcommittee Mr. Corn-Revere described the
experience of his client, an ISP that was required to install Carnivore
when presented with a trap and trace order. He detailed his client's
concerns that a trap and trace order in the context of the Internet
revealed information that Congress did not contemplate when it
authorized their limited use. In the traditional telephone context,
those orders reveal nothing more than the numbers dialed to or from a
single telephone line. In the Internet context, these orders and
certainly Carnivore, likely involve ascertaining the suspectÌs e-mail
address, as well as header information that may provide information
regarding the content of the communication.

As we have stated previously, the ACLU does not believe that it is
clear that the Government can serve an order on an Internet service
provider and obtain the e-mail addresses of incoming and outgoing
messages for a particular subscriber.  Further, it is not clear whether
law enforcement agents use or should use authority under the pen
register statute to access a variety of data, including Internet
Protocol addresses, dialup numbers and e-mail logs.  We certainly do
not believe that it is clear that law enforcement can install a super
trap and trace device that access to such information for all of an
ISP's subscribers.

In light of the new revelations about Carnivore, the ACLU urges the
Subcommittee to accelerate its consideration of the application of the
4th Amendment in the digital age.  Legislation should make it clear
that law enforcement agents may not use devices that allow access to
electronic communications involving only persons other than a specified
target for which it has a proper order. Such legislation should make
clear that a trap and trace order served on an ISP does not authorize
access to the contents of any communication  including the subject line
of a communication -- and that the ISP bears the burden of protecting
the privacy of communications to which FBI access has not been granted.

We would be happy to work with the Subcommittee on drafting legislation
that protects the privacy rights of Americans.

Sincerely,



Laura W. Murphy
