Yeah, long time, but rest assured, I'm following.
I know they dismissed it, but I was just curious if they even admit to still having it and having it solely because they consider it connected, in some fashion, to the Cooper case. If that's the case, then what they say to the public "it's not Coopers" and what they believe internally even if only a possibility, are two different things. Which, would then seem, sadly, to be just one more thing in Cooperville that cannot be relied upon, the one place you should be able to go for hard answers and not conjecture, the FBI, is, seemingly, a dead end.
Is there some statue of limitations that even if a case can legally be considered active under a John Doe suspect, after so many years, say...45...or 50, they should open up all files and evidence for public scrutiny or at least be able to petition for such? It is the FBI, a gov't agency, here to serve the people. The agency is not beyond public oversight. There's plenty of people willing to put some of that evidence thru more detailed analysis, and willing to spend their own money to do so.
There's so very little hard evidence, as being so much time has past, you cannot rely on anyone's personal account of anything that happened as so much of peoples memories can be easily altered even if they don't realize it with all the media about Cooper in the last 45 years. Hard evidence is the only thing that really can solve the case. Sadly, I doubt it will ever be solved.
