  It has been argued that when black holes are treated as quantum systems there
are implications at the horizon and not just the singularity. Infalling
observers will meet a firewall of high energy quanta. We argue that the
question of whether an observer falling into a black hole experiences a smooth
horizon or a firewall is identical to the question of whether Schrodinger's cat
is either in a definite state, alive or dead, or in a superposition of the two.
Since experience with real macro-systems indicate the former, the black hole
state vector is seen to describe a set of decoherent alternatives each with a
smooth horizon and the entanglement puzzle is thereby side stepped.
