When you take a drone out of the case and begin preparations for flight in a public place it is inevitable that you attract a little attention.
The news has been filled with negative reactions to drones. To be expected of course, drones are a new technology bound to attract attention, and the media tend to write about something only when it goes bad. If it bleeds, it leads reporting.
The result has been quite a few reports of negative reaction in public to a drone. Reports of spying or snooping into private property have become common. There has certainly been some hysteria surrounding drones, some justified, quite a bit completely unjustified.
