I'm not sure where you're getting that.
According to the article, "There were 415 human trafficking victims rescued in the county in the past two years, compared to 509 in 2015-2016 and 371 in 2013-2014. According to the OCHTTF report, a full 73 percent were new victims in 2017 or 2018. Of that total, 87 percent were trafficked in the sex trade while 12 percent were in forced labor."
IMO, anytime you can get human traffickers and the people who patronize them off the streets, you're helping to save the world.
And how many of these were just hookers plying their trade?
"Human trafficking victim" sounds better than "hooker" though, right?
"Human trafficking" is a current euphemism for prostitution. If you transport hookers to where the customers are, then you are engaging in "human trafficking".
Why do some women get into prostitution? It's a way to make much more money than they could otherwise, and for drug addicts who are too dysfunctional to work a regular job.
Many are not "saved", they will be back on the streets within a week or so.
