I'm not asking the Transportation Safety Board to assign blame; I'm asking whether the Transportation Safety Board has examined the question of liability in the context of improving safety. If liability were shared more directly with the owners of the dangerous goods that cause a problem, would that have a bearing, for example, on having the owner of that property, those materials, asking much more difficult, much more probative questions of the shippers, paying much closer attention to how that material is being transported? Would that not increase safety?
