After reviewing the discussion in this thread (and other threads),
I must conclude that the whole approach to developing a policy is
flawed.  A policy should represent specifics based on a more
general philosophy, but I don't think the philosophy itself is
clear in this case.  

The first question that must be answered is:  Why continue
developing Mozilla?  I would hope the answer does NOT revolve
around an exercise in computer science but instead reflects a
desire to create a high-quality software application for personal
and commercial use -- an application for the real world.  
If Mozilla is intended for real use, the next question is:  Who
uses Mozilla?  Given my hope for the answer to the first question,
the answer to this question should be:  Anyone who uses the
Internet.  
This means that most Mozilla users are not truly sophisticated
software experts.  

The answer to the second question raises the next question:  In
that context, how are (not how should) CA certificates used? 
Clearly (at least to me), the answer is:  The primary and most
important use of a CA certificate is to provide the Mozilla user
with assurance that (1) a critical Web site is indeed what it
purports to be and (2) sensitive data communicated to a Web server
travels across the Internet securely.  

If this chain of questions and answers is valid, then the Mozilla
Foundation has an obligation to those who use its products to
authenticate not only the validity of each CA certificate in the
default database but also the integrity of the CA's process of
issuing and signing Web server certificates with that CA
certificate.  This requires specific, objective, and verifiable
criteria for authenticating both validity and integrity.  I
advocate third-party audits because those criteria already exist
and are already being applied through such audits.  

No, this does not mean only WebTrust audits.  Earlier in this
thread, I cited a California state regulation that specifies
either WebTrust or SAS 70 audits.  (See Sections 22003(a)6(C) and
22003(a)6(D) under
<http://www.ss.ca.gov/digsig/regulations.htm#22003>.)  Further,
that regulation provides criteria for accepting other
accreditation criteria.  However, until other criteria can be
clearly identified and documented, the WebTrust and SAS 70 audits
are the only trustworthy and reliable bases for accepting CA
certificates.  

In the end, the real question is:  Can we trust and rely on the CA
certificates in the Mozilla default database to protect our
privacy and our assets?  The answer to that question will
determine whether we can trust the Mozilla Foundation, which needs
to clarify the underlying philosophy upon which the proposed
policy should be based.  

Of course, my original assumption -- my hope for the answer to the
first question -- might not be valid.  In this case, Mozilla is
merely an interesting toy; and I will then have to rely on some
other browser for online banking and other critical Web uses.
