Black hole space/time contradictions?

Outside observers (us) can never see an object cross the event horizon of a black hole. Therefore to an outside observer, a blackhole's mass is observed to be smeared just slightly above the event horizon. This is what the laws of physics say, and why it is possible for black holes to radiate (the so-called Hawking radiation). Any statement that matter actually falls through the event horizon is pure speculation and not science as it is impossible to observe. The idea that the mass of a blackhole exists on the surface also explains why the information content, or entropy, of a black hole depends on its surface area rather than its volume.
