EVERYONE states their emergency first. I have ever only seen a HANDFUL of 911 calls where the caller specifies the location.
Most people read this as "what is your emergency"
I think this should be re-worded to "What is your location?" or "Where do you need assistance?" or even "Whats the ADDRESS of your emergency?"
Something to more CLEARLY specify the location.
OR, include the street/area in the 911 call callout. Officers sometimes don't have time to check the MDC map, and, the MDC map doesn't have any sort of sorting or organization to it.
