Zeb, the first responders to the scene such as this are sometimes traumatized. The first responders to he suicide /duouble homicide involving a 9 and 7 year old in the early 90's in my neighborhood is still talked about, and those particular first responders can't come in this neighborhood without getting quite emotional. I saw an ambulance worker crying some years back, then realized why. You are right that we need to be thoughtful and recognize those people in the jobs such as that, who face so much horror in their dally line of work.
My heart goes out to the son of these people who were brutally murdered.
