I think it is disrespectful and unprofessional. HOWEVER, humans will be humans. I've been on several crash sites and trust me, those who do it for a living become jaded and cynical. When you've been standing in the middle of cow pastures in 20(F) degree temps looking over a debris field where a whole family was wiped out due to pilot error, and see the gore, and the subtle human touches like teddy bears, kid's drawings, you build up walls. My wife is a doctor, and they can be even colder when talking about patients among themselves. Is it right? No. Is it human nature? Yes. I try to be sympathic as possible when dealing with loved ones whos family members have died in an accident, and try to remind others around to be as well, but I understand what goes on at the pub at night, conversing with coworkers. Cops, doctors, crash investigators, firemen, etc. etc..
