Your first point isn’t strictly the case though-although I would say from experience that it can be subjective-and of course all things together would raise the risk level.
I cannot see how Faulding failed to understand she was high risk-by the time he was involved it was likely to be a body recovery operation if she was in the water. I honestly don’t see how it would’ve made any difference to his search-
It’s all incredibly tragic for the family. I also do think police across the country will need to review their training on how to manage 24 hour news and the proliferation of social media because things can always be improved. Be nice if the media themselves took this on board too..
I've explained many times why it would have altered his search pattern. He was working on the belief she went to the waters edge and slipped/fell in. On that basis he said her body wouldn't have moved far, so he concentrated on that area. If he knew she was high risk he would have worked on the basis she could have committed suicide by jumping in and/or swam/waded further out. That would have meant she would have been carried downstream.
