I think it's because they're lawyers.
I have decidedly mixed feelings about the legal profession, but most lawyers (especially the "establishment" types most likely to be involved in the CA bar) are *very* unlikely to make deliberately false statements (or to fail to correct a past statement, one they learn it was false).
In defiance of thousands of lawyer jokes, in my experience lawyers lie the *least* of any large group of humans I've encountered – at least if "lying" refers only to the specific denotation of the words, since lawyers also love to split hairs to say something that's technically true. But the distinction between a "hack" and a "database error" is _exactly_ the sort of hair that lawyers love to split!

No matter what ivory tower we're talking about, there's never a reason to be in awe of the top.
