But there are huge benefits of 'eyes in the sky' during a crisis. Car chases in LA are often eliminated when there's a police helicopter because they can simply follow the vehicle safely from a distance as the chopper tracks the car.
Providing overhead visibility support in advance of police arrival is a huge benefit to citizens during 911 calls. If a drone can respond in two minutes, and police are 7-10 minutes away, that's a massive situational awareness benefit that will save lives.
When someone calls for a house fire, having a drone arrive in minutes, potentially with a fire retardant payload, while ground-based fire vehicles arrive 5-10 minutes later, can mean the difference between life and death. At the very least, it provides tremendous information to the fire fighters on the way as to what to expect. They can see the fire before they arrive.
Two major life saving improvements for emergency rooms in the last 50 years were radios in the ambulances so that the ER knew what was coming in, and electronic EKG / vitals relay so that doctors had more precise telemetry of patient status. Drone first responder will have many similar benefits.
