I can see a valid police concern that a drone and live broadcast could influence a live shooter situation. But what about a on-site reporter and live broadcast? Is that illegal?
Seems to me that the law shouldn't limit the drone. Journalistic access to a crime scene or active law enforcement actions shouldn't ever be prohibited. Live broadcasts of such actions sometimes should be.
Frequently the police will set up areas near a major incident for press to report from, but not close enough to see bodies in a wrecked car, etc.
