In my years as a dispatcher (small-town 911 operator), I have NEVER had someone behave that way when calling in for an injured child. And while I've never gotten a call where children have been injured the way Devon and Damon were - I have handled calls where a child has been found floating in a pool; hit by a car two doors from his house; had ingested medication prescribed for an adult; and countless motor vehicle accidents with injured child passengers - the majority of the calls are originated by the mother - who usually sounds quite frantic, but has the presence of mind to LISTEN to what I am saying to her and not scream hysterically. Once it has been determined there is a medical emergency (even an "unknown" medical emergency) the alert tone is already out via the dispatch radio and units are waitng for an address or location (which is up on the screen in front of you - unless the call is from a cellular phone, in which case you may have only a name). The moms I have encountered are usually quite eager for instruction on what to do - in the case of the child found unresponsive in the pool, mom had already pulled him out and placed him on his back; she was on the line long enough to tell me she needed an ambulance, her son was found floating face down in the pool and not breathing, she gave me the address - and then told me she was going to try CPR, she put the phone down and I had no contact with her again until the EMTs arrived and took over.
There is no "right way" to behave when making a 911 call - callers are scared, sometimes injured themselves, etc., BUT, the more I listen to Darlie, the more I hear someone trying to exonerate herself - especially the part where she states "someone... came in here and intentionally did it Darin!" Just her tone of voice and the way she says 'Darin' - [I paraphrased, I cannot remember it verbatim]. My opinion only.
