The rest of the video includes a weird theater of modern surveillance. The helicopter pilots attempt to read the license plate on what they think is the man's car. Then, the man picks up his drone and returns to a house, all observed in close detail from the sky. This is exactly the kind of tracking people worry about drones doing, but here, it's done by a powerful news camera in a manned helicopter. At 7:28, one of the helicopter crew resigns himself to letting the pilot "who almost took us out of the sky" get away--which isn't an unlikely statement. A 2014 study on bird strikes and military helicopters found that birds can cause considerable damage to craft, and noted one anecdote of a bird colliding with an attack helicopter, causing two deaths. While small drones may not cause more harm than birds, it's possible a drone as large as this quadcopter could have caused a crash.
