Who took the building down? Looked like a demolition.
Check out this vid with sound. Building stucco is crumbling apart like snow for 15 seconds or so until building starts falling. You can hear the rumble on the vid.
Good question, I agree something is not right about all this. If it claims it happened due to sinking does that mean the Millennium Tower (Condos)in San Fransisco will come down like that too?
