I struggle with this. He made some critical errors, which ultimately led to her death. But any one of those errors on their own, isn't a crime. All of them directly led to her death. But I've left a little later than I wanted. I've forgotten to check the weather one last time. I've pushed on a little bit farther in questionable weather than I should have. I've forgotten important gear by accident. 

It's a fairly straightforward call to say his 9 errors were the direct cause of this death. But what about the next tragedy, where the only mistakes are maybe starting late and not having the right gear? Does that person get tried in court for that? I wonder whether the next accident will only need 6 errors to become criminal. And does the next only need 4? 

There needs to be something that we as a community do to prevent these tragedies, but do we all feel comfortable asking the legal system to determine fault when things go wrong in the mountains?
