I met this woman author years ago (a liberal, to be sure) named China Galland and she was documenting women and children trafficking internationally, mostly in Thailand and South America, IIRC, but it was before anyone really heard about it here in the US. This was in the 1990s when we met and she had started way before that.
She was trying very hard to get people in Congress to take notice. I remember her telling me how frustrated and angry she was that no one would do anything about it or take meetings with her. She had mountains of documentation. She really put her life in danger and on the line for these kids.
She found all this human trafficking evidence in the process of writing a book on the Black Madonna. She traveled extensively to places were the Virgin Mary was depicted in statutes and paintings as being black. I know that is strange (her doctorate thesis or something) but it's how she came to find out about all these women and children. She said the Virgin Mary was calling out to her to save them.
