Numerical results for the semi-classical stress-energy tensor outside the\nhorizon of a Schwarzschild black hole obtained in the 1980's and 1990's are re-\nexamined in order to better understand the origin of Hawking radiation and the\nimplications for the black hole information paradox. Polynomial fits to the\nnumerical results for the 4D transverse stress are obtained for\nconformally-coupled spin 0 and spin 1 fields in the Hartle-Hawking and Unruh\nstates and. Analysis of the spin 0 Unruh state results clearly shows that the\norigin of the Hawking radiation is not pair creation or tunneling very close to\nthe black hole horizon, but rather is a nonlocal process extending beyond r =\n3M . Arguments are presented that the black hole information paradox cannot\nplausibly be addressed by processes occurring on or very close to the horizon\nof a large black hole whose geometry is close to Schwarzschild.\n
