This is all speculation, that is all true. Something that bugs me is that
the ILS for 31C requires RVR of 4000 or 3/4 of mile visibility. The METAR
from just before the accident pegged visibility at 1/2 mile. Seems to me
that the approach shouldn't have even started.

On the face of it yes, but you're ignoring all the other potential sources
of *updated* weather info.
