Joint dispatch makes sense
Help is a phone call away, thanks to 911.
In most cases, the dispatcher answering the emergency call is in the same county as the caller, but not always. That's because a local dispatch center isn't mandatory in today's technological world.
The 911 dispatcher takes the call, contacts the nearest officer, fire truck or ambulance, and help arrives minutes later. The emergency responder's location, not the dispatcher's, is the key.
