Clayton, you're failing very badly at this, your own poor references undermine what you're claiming, and you apparently don't realize it.
You must slow down for a moment and consider this simple fact: not only was asbestos NOT in most of the towers including WTC 7, but asbestos is found in hundreds of thousands of older buildings in North America, and they mostly are still being used commercially.
Asbestos is only a hazard when renovations are being done. It is quite safe when undisturbed. Case in point (for your reference and understanding) the Queen Elizabeth Theatre in Vancouver is a place I work at all the time, built in the 1950's with a lot of asbestos insulation over ducts and pipes.
The city has hired engineers to determine where it is, and to affix appropriate warning labels to those areas where it is present. You can see the labels as you walk thru the hallways.
But they haven't touched it except where necessary. it's just going to stay in place until further notice.
Really, this is much ado about nothing. It's another example of truthers
a) getting basic facts wrong
b) extrapolating scenarios from those incorrect facts which have no connection to reality, and then treating those scenarios as facts themselves.
Because truthers like yourself do not normally correct their mistakes, these mistakes get repeated on every conspiracy website, years after they've been exposed as incorrect.
Thus someone like you presents this kind of nonsense in 2012, much to the amusement of the readers of this forum. It is indeed flogging a dead horse to correct you once again.
As the CBC documentary commented last week, the internet has been the perfect breeding ground for conspiracy theories - things spread very quickly, and there is often little or no quality control on the info that is spreading.
I suggest you take a more skeptical approach lest you fall prey to all these urban legends.
