Last Monday night on the CBS news Dan Rather mentioned that the truck bomb that blew up in the WTC parking garage in 1993 was loaded with a significant about of cyanide. The bombers apparently hoped that the explosion would push the cyanide through the ventilation system and kill everyone in the building. Am I the only one who had never heard this before? I always thought that attack was supposed to damage the physical structure of the building, and maybe cause it to collapse. But I had never heard the chemical weapons angle on it before. Can anything be read into the fact that this aspect of the story was not widely reported?
