The biggest drug bust.

The article reports that the drug money was laundered into clean, untraceable cash to the U.S. banks and even to the U.S. Federal Reserve. The Atlanta Federal Reserve's branch alone had deposits of $1.3 billion cleared through Panama. Federal drug busters are finding out the source of the untraceable cash. Switzerland, the Bahamas and the Cayman Islands now turn over bank records on demand. The money trail led to the payoff in the U.S. Drug Enforcement Administration's biggest sting operation. The three-year-long "Operation Pisces" produced 387 arrests and, along the way, seizure of $50 million in assets, including $32 million in cash and 28,000 pounds of cocaine.
