I want to be the first to say this.
The main thing that kept the Cooper thing alive, is the lack of information, or inconsistent information flow, from the FBI.
With each month, as more FBI files are released, the whole thing becomes more boring.
It just becomes a case, with "triumph of the nerds" analyzing paper, because all the interesting people to talk to are dying off.
At a certain point, the "facts" aren't going to be interesting anymore. Just dry paper...well actually dried-up pdf files.
I mean, I can't believe people want to say that the FBI has a report of Cooper having cigarette stains on his hands. I think that was an erroneous FBI report late in the game, by someone wanting to compare to a suspect with cigarette stains.
But it will be people arguing stuff like that about inconsistent FBI files in the future..
And that makes it less interesting. i.e. the information kills the beast.
"murder of the impossible"
Some things are no longer interesting, when you know too much.
I'm impressed that Bruce seized on the interesting angle early: i.e. the FBI behavior was as interesting as Cooper's
