Re: They dont want to use the MLAT.
It does seem extraordinary that the US government is attempting to assume the power to compel US companies to break the law in other countries ...
It is in fact worse than that: US government already claims the power to compel foreign companies to break their country's laws. A case in point is the US embargo against Cuba. Under it's terms, a Canadian company doing business with Cuba is required to break Canadian law.
Whatever adjective you might want to apply to Yanks and their foreign policies, neither "shy" nor "retiring" would make the top of the list.
