That's the reason... to grab govern money... not because it is a threat.
Myself, and many (most?) others who follow the topic, doubt there's a real threat from what ever they may turn out to be. But, as always, it may not be as simple as it appears one way or another, some that dependent on what you read and what you choose to believe.
Has not been in the past and see no reason why any phenomenon that we can't even register on clear video yet should be.
That's a different issue and topic. For example, the pilots to made the recent "leaked" vids said they were intentionally made difficult to see. Remember, they returned to the carrier and can watch their own vids. According to them, they were much clearer. I have no doubt they can get, and posses, far better vids they aint sharing with us.
Two, there's a field created around some of those craft, what ever it may be, well established in terms of what cameras and human eyes see, which interferes with radar, cameras, etc. The field is a very strong electromagmetic in nature.
So, there's several reasons we don't get the best vid. Finally, some vid that does exist is quite clear, but the object may be moving so damn fast it's difficult to capture.
There's more pics and vids coming out all the time due to so many phones, etc but I can't even get mine up and running in time to catch my dog doing something funny, much less have it out and filming at precisely the right time a UAP just happens to be there.
Finally, For myself, due to how easy it is for anyone with a phone or comp to fake photos, unless confirmed by someone expert in forensic photography or similar expert analysis, I assume it's a fake. With AI, etc is only getting worse. Even vids are pretty easy to fake for those with the basic skills. I hope telling the fakes from the legit stuff will at least remain.
