Accidents are caused by a chain of events that were able to happen because some defences failed. Mentioning a specific defence (ie. crew experience, CRM, fuel etc..) is not meant to single out a cause, it's just to poit to were defences failet to meet their objective.
By law it's so easy, the commander shall...... So it's all his/her responsibility nowhere however does JAR-OPS say that the company must make shure commanders take their responsibilities. Worse even in many occasions the company consider a pilot who is willing to take a risk (read breake a rule) a better pilot because it helps the company to acieve their goal which is making money.
Detailed discussions into the amound of fuel required is in my opinion bs. we should discuss how to deal with commercial pressure, and how to regain captains authotity because that is were the risk starts.
