The issue here is with drones, in general. What you are arguing for is tighter regulation of the NSA, which may or may not be a valid issue, but is not the issue at hand. The issue here is are drones, as a whole, a threat? Or does the issue stem from those who misuse them?
I can see much farther away with binoculars than I can with a drone. Why does nobody care about them? Are microphones and cameras also invasions of privacy? What about the NSA? I don't think drones should be such a controversy. Punish those who use them irresponsibly, end of story.
