Re: [Debconf-discuss] Please revoke your signatures from Martin Kraff's keys
I think the core issue here is if we deem presenting purchased
identification at an event designed to extend the web of trust
I check photographs, name, age, and expiry dates on ID
presented. I did not include document verification in that checklist,
since it is something I do not think we can do, in about a minute or
less, with no instruments. I have some sample ID that purports to be
for Donald Duck -- with a human picture.

This is the crux of the issue. I have always maintained that
it is possible to fool me; but I assumed that I moved in circles
where presenting puchased identification papers was a phenomena that
did not occur. If presentation of purchased ID's is acceptable, then
the only way of being surew about official papers is to only sign
keys of people who have papers that I can recognize as being
official -- which means, for me, Indian and US passports. And even
then, I am sure the forgeries are beyond my ability to recognize.

By presenting purchased ID's in lieu of official one. Sounds
exactly like the kinds of rationale crackers present -- testing real
world deployments of machines for the peoples own good.

If I can come to you with a purchased ID's are you so sure you
can tell a fakeID from a real one?
Anyone can, thanks to the powers of the internet, find
artisans that can, probably illegally, give you very official looking
documents that are impossible for a lay person to tell apart.

Are you arguing that would be a real world test to see if you
can spot forged ID's, and laudable? If so, when you come u0p to TN
for the food conf, well have a wager. It is possible to fool _anyone_
with high enough quality purchased ID's. And from all reports, the ID
looked pretty darned official.

I think that friends at my work can produce documents that
none of you can detect. I still think that purchasing identification
from non-official channels goes beyond the pale, but I appear to be
in the minority. I'll just institute far harder key signing rules
when it comes to Debian people, since what is commonly accepted to be
nefarious behaviour in security circles does not seem to be the case

I see. I hereby challenge you to detect fake official looking
documents I'll present to you (just ignore the word sample emblazoned
across them, since I got it from work), the next time you are in TN.

These are not poor keysigning techniques, unless you accept
all ID document verification techniques rely on a gentleman's
agreement about not presenting purchased ID's. As I said, I can show
you sample identification that I challenge you to tell me why my name
is not Donald Duck.

Now that presenting purchased Identification that looks
official is in play, I am not sure if passports can be trusted. I
have, for example, no idea what a passport for Cameron looks like --
so really, I can only sign keys from people presenting an Indian, or
US passports, and having drivers licesnses from from MA, AL, or TN.
Unless, of course, presenting purchesed ID's were frowned
upon, and a genteman's agreement existed in Debian to not try to fool
the potential signer, which appears not to be feasible, given the
responses to my concerns.
Since presenting ID's that one has purchased is apparently OK,
this effectively shuts down any key signing between people who are
strangers, or come from different countries.

Do you really have an alternate course you can take, since now
we admit that presenting such ID's are OK, and the person perhaps has
not yet completed their study and published the hoax? (only half ;)
With all the fancy scientists in the world, why can't they just once
build a nuclear balm?
