Professor Peter Dale Scott sees what the rest of us miss. His decades-long investigation of the connections between the hugely lucrative and unstoppable global drug trade and the national security apparatus is unparalleled. The details are also highly complex and a challenge to absorb. Nevertheless, they demand our attention. In this excerpt from his new book, Scott focuses on the troubling relationship between Ronald Reagan’s CIA director, William Casey, and BCCI, a still-mysterious “outlaw bank” with tentacles everywhere, and extensive ties to the drug economy.
