The material by Dan Burisch is pretty interesting, but he seems a bit too cavalier about everything, like one of those friends that entertains everyone with personal stories so amazing because they're actually made up. And yes, he has been very vocal for a very long time. That usually means one of two things: the person is useful to the manipulators, or the person is legitimate but beyond being outright killed.
The thing about Burisch is that everything he says is colorfully detailed, and there are detailed documents also to back up his claims... well, documents that he himself provided. Except the ideas themselves are questionable and anyone who was as deep as he was, would not be out shooting his mouth off without getting his head shot off -- especially people involved in government or military work who later end up spilling their guts in more ways than one. It's the contracts you enter into with that type of work that sign away your freewill and get you eliminated. People that are really involved in that stuff probably work under split personalities, remembering nothing of what they really did after being discharged. Maybe they don't even live on the surface of the earth and don't exist as far as official records could prove. To be involved at that level, and then prancing around on the internet and entertaining room-fulls about his adventures, that just doesn't fit. The guy who came closest to being the real deal concerning underground bases and secret projects was Phil Schneider, and within a year of him speaking out he was found strangled to death in his apartment.
Some people are very critical of Burisch's story and have documented the holes in it, the fake evidence, connections, and so on. My best guess is that it's part of the larger deception happening, and the deception could go so far as to abduct and mind control some people with false memories and subconscious programming so that they sincerely propagate lies mixed into truth. Not sure if that's the case here, but after you dig into it, things don't add up. Even more interesting is how those involved in the agenda often pop up in the same places... Project Camelot being a nice example.
