I just wanted to echo that Vallee's book "Revelations' is something we should all read. I recently bought it on amazon after his interview on the paracast and flew through it in a couple days.
For those of us who are really dedicated to getting as much truth as possible, I think this book can be very helpful in pointing out the crazy level of deception there is on this topic just from the human side alone! For those of us who realize this is a real phenomena, it can be easy to believe most cases that seem to have substantial corroborating evidence.
What Vallee points out and it's something we all need to keep in mind IMO, is that some of the best UFO cases (Rendlesham) may indeed be real events with witnesses but when you look under the surface they also look as though they may have been staged by humans for a particular reaction.
Why would someone spend millions of dollars to stage a fake UFO sighting? In one of the examples Vallee uses, and I can't remember the name of the case but I believe it involved some French kid getting abducted, but essentially my theory after reading it was that some insider paramilitary/government organization was trying to see how much influence a UFO experience could have. In other words, is it possible to instigate a grassroots effort that would eventually effect the mass consciousness via a staged UFO event?
Why also do the latest top dick UFO researches get fed bullshit 'insider' info from a legit unknown source which then is debunked as bullshit? (Dolan beware, don't listen to any anonymous people in your ear!)
Vallee really makes you realize how crazy and deep and confusing and multifaceted this whole scene is. The great analogy he uses which I posted before is that a lot of this human deception is like an 'intelligence onion'.
There are many layers of this onion. In the top layer they want us to believe UFO's are not real. The 2nd layer wants us to believe UFO's are real and the government is hiding it. The 3rd layer wants us to think Aliens are running the world. And so on and so on until who knows what the fuck is true anymore and this probably includes the people spreading the disinfo mixed in with real info.
So I think we should all keep our bullshit detectors on, even for the best cases, and always consider the possibility that something is true, but I would be very hesitant to 100% commit to any particular case unless it was your personal experience given the crazy deception not only from the human side, but also from the non-human's as well.
I think another part of the deception could be that people who have 'real' contact are then fucked with and decieved and maybe even get a bit luny themselves which then discredits them later on. I think it's totally possible Greer, Meir, Sparks and company have had real experiences but then something happened to them. That also seems to be a pattern as well. But it's also possible these dudes didn't get enough attention as kids
