Having known more than a few cops in my day, they also have a vicious sense of humor when dealing with such a situations.
One of the detectives that taught one of my classes showed a slide of a snow covered yard that had some disturbance, and quite a bit of blood. The teacher said something like "We love snow. It gives us a glimpse of exactly where people were. And this [points to blood stain] is what we call a snow angel." Most of the class was appalled. I think they were in the wrong major.

You have to have a sense of humor. It doesn't mean you don't care. It means you're keeping that stuff from creeping into the other aspects of your life.
