I understand what you are saying, but we are also trained in preserving crime scenes. Oh, two weeks ago we were involved in a search for an individual in a 150 acre park. The police had used their dogs and had been searching for the individual for two weeks. My team (my task) found them within 4 hours. They were questioning why we were re-searching an area that they had already searched. I still don't know how they missed him. He was in the woods for two weeks. He did not smell good. It was a crime scene and we handled it properly.
Well, good on you and your volunteers in that case. That is commendable.
