What is wrong with commenting upon the lack of CRM and cultural behaviour when this is known to be a real factor in a number of accidents over the years in many non western cultures? So, yes absolutely the two do go together as the combination has shown to be a major factor in past accidents and should be considered especially in light of the information available.
What gets me is the fear of being politcally incorrect and not asking questions or commenting on issues that could have a positive impact on future accidents. The comments above on this are perfectly fair in light of the information currently available on the accident in question.
