If you hang out at Port Everglades and watch as the three immense cranes offload containers from supercargo freighters, you're witnessing the refueling of South Florida's economy as needed goods and products and raw materials pour into the region. What you may also be watching is the feeding of a drug habit. Last year Port Everglades was unmasked as a major point of entry for cocaine shipments into South Florida, as no fewer than three smuggling rings jockeyed for position and profits within the port. Eventually an investigation by the federal Drug Enforcement Administration and U.S. Customs Service resulted in charges being filed against 29 dockworkers, port security guards, and associates. Even as they basked in a successful bust, however, port authorities admitted they were no closer to winning the war on drugs. Because it's impossible to comb every single container coming off every single ship, the drugs may still be coming in.
