I think inside job isn't the term I would necessarily use even if people on the inside were involved. I don't necessarily think the whole government is guilty, but.. I do think some people in the government and high levels of power know a lot more than they act like.
And yes it would be horrifying and is either way. But even more so if our own government was involved. I agree.
I pretty much agree with everything else you said, except I think Trump is sort of one of them, and if he really wanted to release those files he would have tried by now, so I think he just said that to help get himself elected. Or to.. Appease certain groups of people at least.
