Catch-22

So if you're not into 'conspiracy theories' just go away, these aren't the posts you're looking for.
If on the other hand you'd like to hear a crazy person ramble about something that you haven't come across before: perfect.

I'm doing this as a bit of a test: I'm fairly confident that my theory is correct, and I'm waiting for a letter from some official anti-terrorist unit to confirm that I am correct. If it is true and they do nothing, then this information would be available to any would-be terrorists, but if they ask me to cease and desist (which I would do, I suppose) then I have my answer.

Here is my theory in short: A significant number of very tall towers put up in recent-ish history are already pre-wired and dynamited for the eventual day that they will need to come down safely, without taking out their neighbours in the downtown core. They may need to come down in an emergency (such as tower 7 (Salomon Brothers tower) on September 11, which, as you may recall, was the 47 story building that wasn't hit by a plane, yet came down that day as well) or simply at the end of their life-span.
Watch it come down at 8:01, also nice is a quote at 9:12. watch a planned demolotion. watch a compilation (note the mechanical room on the top collapses quicker than the edges). or watch one interview where the guy basically puts it out there...
Snopes lists a ton of different items about 9/11 but not a single one about planned demolition.

So, based on a little bit of info, and a lot of imagination, I'm going to go ahead and tell any would-be terrorists: don't bring your own thermite or TNT, it's already supplied! Just find the controls and then set them off! It might be hard to figure out what height and age would be ideal, so I'll go ahead and post a fairly conservative estimate: less than 40 years old, and at or above 40 storeys in height. Go find the wires and controls to blow the whole thing down.

it might not be true
it's fun to think it is, but...
not in canada?
