Criminal money launderers are becoming ever more innovative matching and I suspect, in many cases surpassing law enforcement efforts and anti-money laundering regulations. Among Colombian money launderers, for instance, there's evidence of increasing use of commercial trade. In one case, drug profits earned by the Cali cartel purchased construction equipment in the United States, which was then shipped to Colombia. This gave the cartel an enormous advantage in the Colombian construction business both in terms of quality of equipment and in unit costs. There are also indications that complex financial instruments are being utilized by the cartels. Colombian cartel financiers are thought to have bought impressive amounts of their government's long-term debt instruments.
