Re: I don't envy the FAA's task
Drones with cameras and drones with guns, those are real issues / dangers but probably largely outside the scope of FAA regulation. There will probably be a whole separate set of regulations / laws from law enforcement to privacy to telecommunications (radio spectrum) governing unmanned aircraft, with more needed as time goes on for complications that have yet to arise.
The FAA's main charge is to make sure these things can operate safely in public airspace (which I guess might include that they're not carrying gun turrets), with some reasonable accommodation for hobbyist / noncommercial use of small unpiloted planes that fit into the traditional model aircraft niche. I think that's part of the White House's logic behind having another agency take the lead on the privacy / bandwidth issues (assuming the Politico report is correct).
