Personal-use drones have been wildly popular since landing in the consumer shopping scene in 2014. The unmanned-aerial devices seem to keep trending upward in this upcoming holiday season, with the Consumer Technology Association expecting 9 percent of all holiday technology buys to be drone-related. Drones seem to be a prime buy for potential commercial purposes as well: Amazon has long flirted with the idea of using drones for package delivery, and last week, Apple announced that it planned to bolster its mapping data using aerial drone imaging.

But as drones become increasingly pervasive and expand their use, legal experts find that some key concerns remain. Because drones are almost always outfitted with cameras, privacy questions rank highly among attorneys looking into drone flight.
