I don't know about that. I was a police officer for 17 years and Homicide is often called during a death that doesn't have an obvious cause. I don't mean the actual physical injury, but what lead up to the injury or fatal event. They have the experience and equipment to do a complete job.
Many deaths will be ruled accidental or natural and not a homicide, however if you get the information ahead of time while at the scene you don't have to go back and try and collect evidence that may be gone after the fact.
I just finished listening to the unedited 911 call. I can only give great praise to both the call taker and the caller. The call taker did an awesome job of getting all the information, keeping the caller calm, and providing emergency first aid instructions to a seemingly untrained non medical person.
The caller, while obviously under a lot of stress and anxiety handled the call very well. He provided information to the call taker, continued to clear the track of ride cars to make it easy for medical responders, repeated the medical instructions to those actually performing first aid on the victim, and never lost control.
Great job to all involved. The victim died, but it wasn't from the lack of any care he failed to receive on the scene.
