Well, I suppose if governments admit to conspiracy, they cease to conspire, no? A conspiracy by definition is an act wrapped in secrecy. There's no secrecy once the perpetrators admit to the act.

I don't know to what extent 9/11 was "an inside job" or even whether it was an inside job. It sounds plausible enough. I certainly don't understand why so many people dismiss the possibility out of hand. The State has its own interests apart from the people's. Americans seem willing to believe this about other States but not their own. Presumably, the Great God Democracy ensures the good intentions of the American State, whatever its foibles and failings.

In the Internet Age, the governments have no choice but to come clean. The theories are out there and more and more people see them as plausible. Admitting to false flag operations is a way for the State to vaccinate the populace against the tinfoil hat crowd. "See, sometimes we do conspire, but we're trying to advance the Greater Good when we do: fighting terrorism, communism, fascism, burqas, drug-smuggling, high golf scores, etc. We'll keep this kind of stuff to a minimum. You know we will now that we've admitted to it."

To avoid the tinfoil hat label, most of us will accept this handful of admissions and scoff at all the other fever-swamp allegations of high crimes and misdemeanors. But if the State admits it conspired to commit this handful of criminal acts, how can we be so sure they haven't conspired--and continue to conspire--more that they haven't admitted to?
