Good comment Frank.  It can be done. A law suit was filed in San Francisco today by two trafficked aliens.  It read like a nightmare.  Maybe Civil Beat will cover the lawsuit filed in the Federal District Court in San Francisco.  I remember the defendants name were Fatah and Sirohan (sp) and the ship owner was a Vietnamese guy that owns the Sea  Queen II.  That is a Honolulu based boat.  The facts were reported on television this evening.  It was written up in several California papers. Both of the plaintiffs are licensed to fish in the State of Hawaii by the DLNR, Division of Aquatic Resources.  I hope that things change. 
These men need showers and restroom facilities while on land.  Detained on a vessel for 6 years is a bit much.
