Federal authorities arrested 20 people, most of them current or former longshoremen, on charges of smuggling massive amounts of cocaine through Miami on cruise ships or in cargo containers from Colombia. Two other suspects, Ernie Acosta and Fernando Martinez -- alleged to be the main importers of the cocaine -- are wanted as fugitives. All 22 were indicted on trafficking or conspiracy charges in three related operations aimed at breaking up smuggling through Miami's busy port. "The longshoremen involved have had their grip on the Port of Miami for far too long and these cases go a long way to loosening that stranglehold," U.S. Attorney Guy Lewis said. The Port of Miami is a hub for trade with Latin America and Europe and also calls itself the capital of the cruise industry.
