"It’s still far too early to know exactly how FAA rules designed to provide safety and efficiency will affect unmanned aircraft privacy. Commercial UAS operation in the United States is not yet permitted, and the number of law enforcement organizations that have received FAA authorizations for operational (as opposed to training) UAS use is still very limited. And while there is a large and growing community of “drone” hobbyists, the overwhelming majority of them fly safely and in a manner respecting privacy.
However, as unmanned aircraft use increases there will inevitably be instances in which UAS are operated by private individuals, paparazzi, companies, and law enforcement agencies in ways that raise privacy concerns. Determining whether those uses violate reasonable expectations of privacy will sometimes start—though certainly not end—with an inquiry into whether the UAS was operated in compliance with FAA regulations."
