It's very difficult to determine that the time the SARs resources came on scene was the difference between life and death. The assumption is that if they had been there a little earlier, the individual might still have been alive, but whether or not that individual could have been kept alive...maybe there were serious injuries and it was just a matter of time. There is a statement in my brief on this. Sometimes no human intervention can change the outcome. There may be a case where we know the individual succumbed to his injuries within a half hour of the SAR reporting, but whether or not, if they got there half an hour sooner...and that's why there is an uncertainty, there is no question.
