Canada bought some of Governor Clinton's friend's program's contaminated blood, and Canadians were infected with HIV.
MiaT kept the details...iirc...
Canada was the first victim. But a Canadian pharmaceutical, guided by various Canadian government and Red Cross officials, was instrumental in processing and exporting the same diseased blood -- that's how it got back here.
The RCMP has been on the case for years, and is, I believe, hot on the trail of some of the criminals involved. American press media ducked the story (presumably to protect Clinton), but the Canadian press has not at all been shy about covering it. The tainted blood scandal has been front-paged up there for a good fifteen years.
