We are taught from a young age to dial 911 in the case of an emergency. But what would happen if you called that number and you didn't get the response you needed?

These delays ended with tragic consequences where people died. W-Five investigates this sometimes overworked and understaffed service and the major mistakes that staff have made that ended in tragedy.
