The "Enemy of the State" concerns are a bit unfounded. There are already plenty of laws covering the uses of airborne cameras, FLIR, and electronic eavesdropping. We are actually on a good trend with the judiciary since the SCOTUS ruled against warrantless deployment of GPS trackers.
Another quizzical problem for the Court. Is it OK to watch something on the ground robotically with the same resolution that, say, a human in a zeppelin would have with the naked eye?
