Another person who called 911 for assistance has died, as the dispatcher sent rescue to the wrong house.
First they lost 18 minutes figuring out the right street, but even after the confusion (Wells ... Wales, I can see the confusion) it took another 19 minutes before an ambulance was dispatched!
This person died from medical issues, maybe she could have been saved.
Imagine the same situation with somebody beating down your door, or with an abusive spouse ... a burglar or anybody else who intends to injure or kill you; how long would it take for you to get through to the operator, would he/she be able to send help immediately and how fast would help arrive?
Survive untill it does.
