Oddly, that's what the article says about the U.S. military. It--particularly the USAF-is accused of pointing to squirrels as a means of deflecting attention away from UFOs.
The question is, why? What are they trying to hide?
If they were trying to hide classified technologies, they could merely say, "talking about this matter might reveal classified secrets." But they--again, particularly the USAF--have undertaken a program to destroy the careers of their own pilots, etc. who have reported sightings TO THEM (the USAF).
Their behavior raises more questions than it deflects.
The Air Force way of protecting technologies is not just to classify them, but to classify their existence and even that they are working on things or testing things or classify the existence of places where they test stuff. So when someone sees some strange thing flying around in some strange out of the way place you call it a UFO and classify everything about it and make the poor soul who decided to talk about seeing something look like a raving lunatic who was abducted by little green men in Roswell.
As for the rest of government there should be about zero classified information. That would include things such as grand juries, evidence in active crime investigations. People should have the right to act in their best interests. At no time is there the best interest for government or people in government.
As for secrets, that applies to the American people all the time. Government needs to know nearly nothing about our lives. Every ten years government is allowed to count us. We should have heated debates about what else government really needs to know about us and formulate laws in a way that do not require government to know about our individual lives beyond titles of ownership. The government does not need to know if I am married, have children, my profession, my earnings, my investments in domestic businesses, my ownership of weapons, my avocations or anything else.
When you starve government of information, you starve them of control. When the people have near total information about government then people can control government. It is the key to freedom and liberty.
