While I don't doubt that many
unsavory individuals have been
trained at the School of the Americas, one thing depserately needs saying here:
Osama bin Laden was not trained at the School of the Americas.
In fact, bin Laden himself has said in interviews that he never received American training, in the US or otherwise. The anti-Soviet mujahedin forces were indeed heavily encouraged and armed by the United States, but the vast majority of Muslim fighters never saw this support firsthand. "Neither I nor my brothers saw evidence of American help," Osama said in 1993.
Moreover, I have not been able to find any trustworthy evidence that Osama bin Laden has ever been to the United States at all, even as a child. Perhaps it would nicely fit some people's agendas if bin Laden were trained at Fort Benning, but once again that pesky thing called the truth gets in the way, spoiling the ironic fun for all.
