From Mashable. I'd say that this artist, as talented as he is, is a pretty good candidate for a FAA cease-and-desist. I see no "liberal interpretation of FAA regulations" what would have made these flights permitted. Excerpt:
The three-minute video above is called Our Drone Future, by designer and musician Alex Cornell. It was filmed on a GoPro attached to a DJI Phantom and flown around San Francisco landmarks; Cornell says he shot it with "a liberal interpretation of FAA regulations."
The genius is in what Cornell layers on top of that footage: a conversation between an intelligent drone known only as 212 and her unseen Homeland Security operator, Ethan. The conversation is as mundane as air traffic control, but hints of menace start to poke through.
We learn that the drone can scan for malicious intent; it can detect stress levels across an entire neighborhood and make a crime prediction a la Minority Report. She casually reveals herself to be weaponized. And in a twist ending, we learn that San Francisco "civilians" are also armed and starting to fight back against the drones.
"Our Drone Future explores the technology, capability, and purpose of drones, as their presence becomes an increasingly pervasive reality in the skies of tomorrow," writes Cornell. He doesn't explicitly identify the drones as belonging to Homeland Security — but the HSA logo is right there on the drone control screen.
