OMG! You cracked the case! You'll get your detective shield any day now!
Are you some type of expert on how buildings are supposed to fall? I'm sure they were rigged to blow by evil invisible explosives experts, with invisible equipment, TONS of invisible explosives, miles of invisible wiring, etc.
See where I'm going with this? Think about it, and do some research on controlled demolition, because anyone who thinks this was an "inside job" likely hasn't looked into it.
