One issue here is the overlap in the term "Human Trafficking" and good old fashioned vice squad arrests. Anything in the single digits leads me to believe it is just pimps and hos and small time brothels - i.e. not of pizza level international significance.
That is what I am saying. Many of these "trafficking" arrests are just the persecution of consenting adults making a business arrangement that should be legal but aren't, thanks to universal suffrage. Prostitutes are neither criminals nor victims, ceteris paribus.
