For at least half a decade, the storied British colonial banking power helped to wash hundreds of millions of dollars for drug mobs, including Mexico's Sinaloa drug cartel, suspected in tens of thousands of murders just in the past 10 years – people so totally evil, jokes former New York Attorney General Eliot Spitzer, that "they make the guys on Wall Street look good." The bank also moved money for organizations linked to Al Qaeda and Hezbollah, and for Russian gangsters; helped countries like Iran, the Sudan and North Korea evade sanctions; and, in between helping murderers and terrorists and rogue states, aided countless common tax cheats in hiding their cash.

"They violated every goddamn law in the book," says Jack Blum, an attorney and former Senate investigator who headed a major bribery investigation against Lockheed in the 1970s that led to the passage of the Foreign Corrupt Practices Act. "They took every imaginable form of illegal and illicit business."
