Very quickly, let me ask you one last question, gentlemen.
A lot of Canadians are writing to me and many parliamentarians at this table saying that liability for this risk should be shared between the railways and between the folks who own the dangerous substances and goods.
What is your position as the two largest carriers—$16 billion last year in gross revenues—on sharing the liability? You are carrying a lot of it now, about $1 billion each in insurance liability, although that figure is not fully disclosed. Should the folks who own the dangerous substances that are shipped on your railways share in the legal liability if there's an accident?
