I don't consider people running out of water/nourishment, not being able to secure a crime scene or getting a deputy or cadaver dog, "petty".
People were instructed to bring plenty of water and food for themselves. You find something you were to mark it and move on the team lead was the person to be debreifed with the info found. You had no reason to WAIT for someone to check it out. Mark and move on............. Apparently, your group did not follow instructions, and yes I consider "food and water" petty issues. If CSI, dogs, LE were not available it was the TEAM LEADER to bring it to the attention of the de-briefers and they gave the MARKED AREAS to the proper jurisdication, the police dept or the sheriff's dept, Forensic's or a search dog was sent to the area. Every team was not given these people on the spot due to the large amount of TEAMS going out. When we did find something we thought was important we called another TEAM LEADER in out area......... and we went to pick up the CSI person. My TEAM LEADER spoke to a sheriff at COMMAND CENTER to ask for verification our spot was checked.
We went to McDonald's for lunch and to our surprise we were given a 50% discount. Instead of going back to the Command Center for more ice.... the manager offered us ice for out coolers and gave us water. Ask and you shall receive................ Self-reliance is an important issue when dealing with the unknown.
