I posted this short clip from CNN's live coverage on September 11th. It is a press conference with then-Mayor Giuliani and he is asked specifically about potential danger from exposure to asbestos in the dust.

Conspicuously, the firefighter to Giuliani's right leans over behind him, puts his hand to his mouth and appears to speak... at the same moment Giuliani turns his head and looks in that direction.

Then gives his answer to the question which was a complete lie. He said the "health department" (NYC Health Dept I presume) has "tested" and they are not concerned. What test was it that could have possibly showed anything but highly toxic chemicals given what we know now?

Do we know what test he might have been referring to?

Why was it so important to continue the clean up that the Mayor needed to give false assurances about the toxicity of the area?
