Then there would be no “private” investigators. They don’t work for free.
The researchers are volunteers. Spending their own money, their own time, their own energy. That is the fact. If someone was paying them, they’d be able to do more. They are private people, investigating, that’s what I meant.
And even professional private investigators don’t reveal all their findings and sources publicly until the time is right.
Private investigators don’t generally alert the subjects of the investigation as to their findings and the tracks they’re following.
So if your "private investigators" are actually volunteers then I see no reason why they wouldn't come forward with anything they've found either.
Take the issue of Fast and Furious as an example. Mike Vanderboegh and David Codrea were "volunteer researchers" and they 'showed their hand' when they found out what was going on. Were they wrong in going public with what they had found out even though it wasn't "the whole kit and kaboodle"?
Obviously not. The same thing, IMO, applies here.
