The pharmaceutical giant Bayer sold a drug for hemophiliacs that ended being contaminated with HIV. Once learning of the contamination, instead of ceasing sales entirely, the company choose to only discontinue the drug in the US (where the evidence of the contamination and associated deaths had come from) and proceeded to market the product in Asia and Latin America. Many patients contracted HIV and ultimately died of AIDS because of this decision. To my knowledge, no one from Bayer has ever been prosecuted.
