Secondly, if I'm not mistaken, the FAA would require a second person
whose sole duty it would be to observe the drone's operation to assure
there would be no conflict with full-size manned aircraft, as is
mentioned in this 25 year old Advisory Circular:

ADVISORY CIRCULAR AC 91-57
MODEL AIRCRAFT OPERATING STANDARDS

The sheriff's department intends to operate their drones over
congested urban areas, not at a designated RC field as is usual for RC
model aircraft. If an engine out incident, loss of control, or
structural failure should occur in a densely populated area, citizens
could be injured by the drone.



The FAA does not 'require' any observers or assistants.

There is also no requirement to fly at 'a designated rc field.'
