  We examine the basic assumptions in the original setup of the firewall
paradox. The main claim is that a single mode of the lathe radiation is
maximally entangled with the mode inside the horizon and simultaneously with
the modes of early Hawking radiation. We argue that this situation never
happens during the evolution of a black hole. Quantum mechanics tells us that
while the black hole exists, unitary evolution maximally entangles a late mode
located just outside the horizon with a combination of early radiation and
black hole states, instead of either of them separately. One of the reasons for
this is that the black hole radiation is not random and strongly depends on the
geometry and charge of the black hole, as detailed numerical calculations of
Hawking evaporation clearly show. As a consequence, one can't factor out the
state of the black hole. However, this extended entanglement between the black
hole and modes of early and late radiation indicates that, as the black hole
ages, the local Rindler horizon is modified out to macroscopic distances from
the black hole. Fundamentally non-local physics nor firewalls are not necessary
to explain this result. We propose an infrared mechanism called {\it icezone}
that is mediated by low energy interacting modes and acts near any event
horizon to entangle states separated by long distances. These interactions at
first provide small corrections to the thermal Hawking radiation. At the end of
evaporation however the effect of interactions is as large as the Hawking
radiation and information is recovered for an outside observer. We verify this
in an explicit construction and calculation of the density matrix of a spin
model.
