  We show that the entropy created by Ohmic dissipation inside an accreting
charged black hole may exceed the Bekenstein-Hawking entropy by a large factor.
If the black hole subsequently evaporates, radiating only the
Bekenstein-Hawking entropy, then the black hole appears to destroy entropy,
violating the second law of thermodynamics. A companion paper discusses the
implications of this startling result. Bousso's covariant entropy bound is not
violated.
