"In July 2008, for example, the FBI and DEA supported Canadian law enforcement in the arrest of eight people, including a customs agent, suspected of smuggling cocaine and marijuana, contraband cigarettes and illegal immigrants over the Quebec-New York border. This underground network reportedly ferried hundreds of kilograms of cocaine from Colombia into Canada via the Saint-Bernard-de-Lacolle border crossing. This is one of many investigations along our northern border.
"In fact, in FY 2009 alone, FBI field offices along the nation’s Canadian border conducted nearly 300 public corruption investigations. A corrupt border official might think that a bribe is sufficient payment for allowing a carload of drugs through the nation’s borders. The ultimate cost, however, might be significantly higher if that carload includes members of a terrorist cell or ingredients for a weapon of mass destruction."
