E = mc2 is a conservation law but not necessarily an equivalence law. The debate on blackholes not destroying information hinges on space travelling faster than light - so light in it can't escape. Some of our equations (Neil Turok) have it that only quantum fluctuations survive the big crunch. I am not sure the laws of ohysics prove information is not destroyed.
