They're using it to search for "human trafficking", by which they seem to mean adult women having sex in exchange for money. Oh, sorry, adult women who describe themselves as "latina" having for money - mustn't forget that part. (Seriously. Look at the pictures in the article.) Minor details like whether the women in question are actually trafficked, or whether they should be deporting them right back into the hands of the people who trafficked them if they are, have never been terribly important to the police in the US. This will be used to hurt vulnerable women.
