First of all crimes are not hundreds or thousands of meters away, or moving very quickly, or erratically.
UFOs almost always are. Cell phones are very good today, but even then if you don't know how to take a good video of something far away or moving, you can easily fuck it up.
And there are actually a ton more videos. I'm on UFO reddit and there is stuff posted there constantly, and there have been tons of videos never solved. There's about 40/20/40 skeptics, middle ground, believers there and it's a laughing stock. If the video is bad? "Why do we have bad video quality in 2025??" If the video is good? "Must be CGI!" People will constantly pivot to protect their previous views with very little room to evolve toward the middle open minded group.
