Who should pay the cost of visiting dignitaries?

Keeping George W. Bush safe on the Canadian speaking circuit is on track to cost the RCMP more than half-a-million dollars this year, as taxpayers foot the bill regardless of whether they buy a ticket to any of the former U.S. president's exclusive events. Mr. Bush is following the lucrative path of his predecessor, Bill Clinton, making big money as a speaker-for-hire with regular stops in Canada. But as Mr. Bush prepares for three Canadian speeches next month, new figures show there's a big difference between a Bush speech and a Clinton speech when it comes to the public purse.
