One of the most common government ploys is to send out “whistleblowers” to get a message out that they want gotten out unofficially, but with some sort of official “authority”.
This has all the hallmarks of that.
Do you have a preconceived opinion about what the UFO stories are all about? Have you already concluded that it is a government disinformation campaign and that's all?
If you have already made up your mind, every piece of information you consider will confirm your position...and the ones that might contradict your position will be ignored.
That's the way the human mind works.
Confirmation bias is a powerful thing.
