At that point, Dorado was swept away by the rush of people fleeing down the stairs, and Mr. Rivera found himself on his own for several minutes amid the pandemonium. But then the unexpected occurred, in the form of a familiar, fuzzy nudge from knee-high.
Granted we had never seen a tragedy such as this in our lifetime and I personally do not know what it was like inside the WTC during all of this, but... There's something disturbing to me about a blind-man having to rely on his dog for help in a situation where so many people (read: supposed human beings) are present.
We watched this particular story unfold right here on FR. The blind man changed the story a little bit after it happened. During the walk down, he was assisted by many people, of course. People are uncommonly kind to blind men with white canes or guide dogs.
