The fact that you are using an anonymous remailer itself reveals
PER SE your lack of faith in your ability to back up these words.

** She (he?) supplied the message from Google. Check it youself.

Not relevant. A repost from google is a discrete publication event.

As an aside, the stakeholder owning the email address in question
may request Google to remove the posting from their archive, and they
will do so.

Be advised that describing a person as a rapist is libelous per
se in most states in the U.S. In libel per se, the person who made
the remark must prove the remark true,

** He wrote it.

Not established as fact. Your belief that is fact does not obsolve
you of responsibility for publishing it.

Finally, and most annoyingly:

WHAT THE **** ARE YOU DOING POSTING THIS CRAP ON REC.PONDS?!?!?!
