ABOARD THE HIGHSPEED VESSEL SWIFT (AP) — Drug smugglers who race across the Caribbean in speedboats will typically jettison their cargo when spotted by surveillance aircraft, hoping any chance of prosecuting them will vanish with the drugs sinking to the bottom of the sea. That may be a less winning tactic in the future. The US Navy last Friday began testing two new aerial tools, borrowed from the battlefields of Afghanistan and Iraq, that officials say will make it easier to detect, track and videotape drug smugglers in action.
