As someone who values my civil liberties, I would caution everyone to curb your enthusiasm (if you have it) for commercial / delivery drone use. It’s only a matter of time, if you ask me, before modern day fear-factors drive politicians to demand that the FAA instruct Amazon, et. al. to install security cameras on all drones as a condition for licensing them to use “U.S. airways.” And you know that if the delivery companies are saving money on drivers salaries and benefits through the use of drones (another strike against drones), they will capitulate and give in to government demands.
