Query: Causal Patch Complementarity: The Inside Story for Old Black Holes   We carefully analyze the causal patches which belong to observers falling
into an old black hole. We show that without a distillation-like process, the
AMPS paradox cannot challenge complementarity. That is because the two
ingredients for the paradox, the interior region and the early Hawking
radiation, cannot be space-like separated and both low-energy within any single
causal patch. Either the early quanta have Planckian wavelengths, or the
interior region is exponentially smaller than the Schwarzschild size. This
means that their appearances in the low-energy theory are strictly time-like
separated, which nullifies the problem of double entanglement/purity or quantum
cloning. This verifies that the AMPS paradox is either only a paradox in the
global description like the original information paradox, or a direct
consequence of the assumption that a distillation process is feasible without
hidden consequences. We discuss possible relations to cosmological causal
patches and the possibility to transfer energy without transferring quantum
information.
