Sometimes you find things in the strangest places (my local):
"[The 9/11 first-responders and rescuers] were exposed to a stupendous mix of compounds, according to clinical studies: soot produced by burning jet fuel; clouds containing cement dust, glass fibers, asbestos, lead, hydrochloric acid, poly-chlorinated biphenyls (PCBs) and pesticides; deisel exhaust from first-response vehicles; and smoke produced by both underground and above-ground fires taht were not extinguished for three months."

How could jet fuel fires burn for three months, especially went it rained for nearly a week after 9/11?
And why did the government tell them the area was safe?
