There’s a universal truth in government: Nothing is secret. Any conspiracy falls apart in short time, because government workers can’t keep secrets. So if there were staged terrorist attacks, it’d be outted in a short time, likely accompanied by audio/video of the principles involved.
It’s why 9/11 conspiracy idiots fail always, along with the Moon Landing Was Staged crowd. It is impossible for these secrets to continue without it being spilled.
Little things, no one cares about? Oh, sure, the ‘secret’ might be kept, mostly because the reporters that hear this babbling just don’t think it important enough to publish.
15 years ago, I would have agreed with you. Then came OKC and TWA 800.
Not necessarily; a small group “in the know” whose members were in powerful positions AND who kept the secret could get pretty far along before they were discovered.
Also, even if they were ‘discovered’ by one or two people they could act indifferent/as-if-he-were-a-nutball and thereby “keep the lid” on the plan.
