I dated a police officer. It is part of their job to be desensitized to this type of thing. It is not that they do not have any feelings, they most certainly do. They have a very, very, very difficult job. It takes a special person to sit there and try not to be human. They are human. It just gets bottled in. They are trained to desensitize. So are the military. But, believe me, they come home and let it out. At least mine did. He tried to bottle it up, but it needs to come out and I was there for him.
