Going to a funeral and gazing at someone laid out is one thing. It is a clean and acceptable environment. However, in the South we had a term called "bad dead." This often covered the major trauma, putrid, or aromatic moments occurring sometime after death. These are the ones you would like to forget about but don't. The police academy in its response to prepare you may show you the photos of trauma, maybe a video of an autopsy, or may even have you visit the neighborhood morgue. Try though they do, they do not have a vial of "essence of dead man" to give you the full effect. So what do you do?
I have heard of some who went to see scary horror movies in preparation. Does not work; save your money. For in the theater, you can shut your eyes and hope the movie moves on—and it does. Your initial shock was from two avenues—sight and sound. So you shut your eyes and covered your ears. Great, however there is no stopping the smell of putrid flesh, it clings to your uniform and sets in for the day with you. Movies do not come in "smell-a-vision."
Remedies of Old
Today many forensic teams have respirators or call fire or rescue teams for breathing apparatus to use. Great idea. But you as a recruit will be the first in won't have these wonderful items readily available.
One of the best tips I have seen was practiced by an old homicide detective colleague of mine. He kept in his car a jar of whatever menthol vapor salve he could purchase. You know, the type you smear on you when you have a cold. Copious amounts around the nose, a glob in a handkerchief or mask, and he was good for the investigation. Another old detective kept cheap men's cologne and covered himself and then a handkerchief as well. Sometimes his cheap aftershaves were worse than the crime scene.
