I think he meant "seeing violent death". There is a huge difference between viewing already dead people (morgue or funeral) and witnessing violent murder. Emotions and feelings (or chemicals in the brain) that are involve are completely different and have different affect on people. During violent death you will get adrenalin rush witch mixed with fear. This tends to make a lot more permanent imprint on to your memory then sorrow and pain witch you would fill at the funeral.
The fact is that very few Americans will ever see violent death. Thous that have high likely hood of witnessing are trained to deal with it. Doctors/nurses are trained through acclimation over at least 4 year period often longer and have large support network to seek help with. Military does it through "group think" or "mob mentality" in a lot less time 6 month to a year but with less favorable outcome (more cases of PTSD and less of the affected seeking help).
