A reference at CERN itself,
BlackHoles
shows that some there actually want to create black holes using
the LHC which would serve as "a black hole factory". Concerns about
safety are dismissed in one line using the dubious cosmic ray
comparison.
It seems that one of the purposes of The Collider is to verify
the existence of Hawking Radiation which should cause small black holes
to fizzle out before they can do any damage. If Hawking Radiation does
exist then well and good but if not we will be in deep trouble.
