"Wachovia, it turns out, had made a habit of helping move money for Mexican drug smugglers. Wells Fargo & Co., which bought Wachovia in 2008, has admitted in court that its unit failed to monitor and report suspected money laundering by narcotics traffickers -- including the cash used to buy four planes that shipped a total of 22 tons of cocaine... Wachovia admitted it didn’t do enough to spot illicit funds in handling $378B for Mexican-currency-exchange houses from 2004 to 2007. That’s the largest violation of the Bank Secrecy Act, an anti-money-laundering law, in U.S. history."
