There's a morass of conflicting stories, but if you're interested you could start with a close look at [1].
edit: Also, in hindsight, after having been sensitized to the topic in general, the fact that there were exercise/drill/training/simulation operations running at the same time and place where terror attacks hit.
what specifically about that building? in what way do you disagree with the "official" narrative and what is your proof of your counter-narrative and what is your evidence that was suppressed?
It has become normalized and it doesn't connect with something undesirable.
At least if we're talking about surveillance in the sense of "when you call someone or are called by someone, the phone numbers and length of the call are automatically recorded in a database, and everyone's unencrypted internet traffic is collected and/or automatically and manually analyzed by the National Security Agency". If someone says the government put microscopic hidden cameras in everyone's home ceilings, then, yeah, they'll probably be seen as pretty crazy. (A bit less so if they say they're just tapping the cameras in phones / laptops / smart TVs.)
