One situation that sometimes vexes SAR teams is when non-trained "spontaneous volunteers" show up and want to help. These are often friends and family of the subject. Another case when lot of people often show up is when kids are involved. While the extra manpower can sometimes be helpful, the problem is that these spontaneous volunteers are often themselves inexperienced and poorly equipped. It can be very hard in a fast developing incident to sort out who can be an asset to the mission, and who is more likely to add to the problem.
