Gerv et al,
I must say that I find it hard to imagine what retrospective requirement
could be resolved by script and video - "only three people in the room"
might do it.
I though the BRs put stricter requirements on the CA in terms of how it
performs and secures it processes - unlikely to be evidenced by S & V - and
on its Certificate contents and CPs - which presumably could be analysed
post-event to see if they would have complied at the time.
Am I being naive - or have I missed the point somewhere?
Cheers
Richard

If it's OK to issue the opinion based on the script and video only, that
may solve the problem.

Of course, we could just give them a waiver. I'm not raising this issue
because it imperils the operation of our root program; I am concerned
that they may not be the only CA in this bucket.
Possible fixes include: allowing CAs who were not being audited to the
BRs *at the time of root generation* to skip this requirement. Or, if
both the script and video are required for all sane audit regimes
(WebTrust, ETSI, whatever) then explicitly say that it's OK to review
the script and video in giving an opinion.
