It seems that I am one of them.  After the fact, I do have a vague
recollection of being presented an ID of unusual issuance, which may or may
not have been Martin's; and I am told I did not ask for a second ID as I
should have.  Clearly, there is serious doubt that my ID checking standards
that day were what they should have been, whether due to fatigue, or a
feeling of being rushed due to the format, or other factors.  I am grateful
to Martin for bringing this to my attention, though I suppose others won't
feel the same way given that it's my intention now to revoke all signatures
I issued based on that KSP barring exceptional cases in which I can
explicitly recall enough details of the signee's ID to confirm that I have
checked it correctly.

I am not asserting that I should be able to detect any and all forgeries of
official IDs; that's definitely beyond my mortal means.  But I should not be
accepting forms of ID that I can't actually *recognize*, and for forms that
I *do* recognize, there are almost universally legal penalties for forging
such documents.  There is no law against private-issue IDs with a person's
name and picture on them, which means that if I allow myself to sign a key
based on such ID, the cost to a potential attacker to get into the web of
trust -- even the Debian web of trust, not the global web of trust in
general -- is way too low, way lower than the cost that any of us should be
able to enforce if we prioritize security over keyrankings the way we ought
to.
