Amnesty International has called on the Canadian government to arrest former President George W. Bush when he arrives in the province of British Columbia next week. In a 1,000-page memo to Canadian authorities, the human rights group accuses Bush of international crimes, including torture, and asks that Canada either prosecute or extradite the former president for violations alleged to have taken place during the CIA’s secret detention program between 2002 and 2009. Bush is visiting British Columbia to address an economic forum. Earlier this year, he was forced to cancel a planned trip to Switzerland after human rights attorneys threatened to take legal action against him for sanctioning the use of torture.
