I would ask that you try to research the matter independently first.  It is out there in the ether.  Go to pier 16-18 and 36-38.  See for yourself.  Observe the state supplied security guard a pier 18. Contact ICE/CBP and inquire.  Call the Harbor Police.  Inquire with the Long Line Association. The article written by the professor appeared in CB.  If you have problems after doing your research write back and I will personally meet you, show you the books and records and introduce you to some of the workers that are trafficked.  Material is plentiful.  Thank you.
