I entirely agree. Since most of us, hopefully, will never experience such a desperate situation nor have any experience of what to do, how can we imagine we would know precisely the best tactical approach to getting our child back safely in a country and terrain that is unknown to us?
They have taken many holidays as a family and know what they enjoy. They understand the capabilities of their children. They may have very hectic busy lives and need to find peace and solitude. They hired in people who do have experience of these situations - the Lucie Blackman Trust - and maintained a respectful and grateful relationship with all the police and searchers. They carried themselves with dignity despite been ravished by fear and despair. They are not responsible for the mis-translations, mis-quotes and speculation in the media. Nor are the police. The police focused their energies on the search and not on managing PR, timelines and messaging for us on WS.
No doubt things could have been done differently - how can anyone know that those differences would have made any difference? A challenging terrain, climate and perplexing scenario. And as has been said many times here: many people who have got lost in this environment are never found. And thats true for the many cases seen on this forum of grown adults who go missing on wilderness trails in the US and elsewhere.
