Isn't the whole idea behind spying to be undetected?

Maybe they are conscious of the fact that we can’t do anything. Did you read about the ones at the military base?

Sightings are at night and the craft have lights. Do they WANT us to see them????

You get to just fly drones around and annoy everyone? Even if that's least of the issues, I don't see why anyone thinks this is okay.

Their own interests. Not a lot of brain power right now, much less critical thinking.
