Low risk victims aren't kidnapped and forced into sex trafficking, despite viral Facebook posts. The last thing they want is someone everyone will be looking for, which is why they tend to target high risk individuals (drug addicts, runaways, homeless, mentally ill).
Typically it's a drawn out grooming process, one that can even take years.
There's no need to grab women off the street, and it tends to be much more insidious.
Traffickers use violence, threats, deception, debt bondage, and other manipulative tactics to force people to engage in commercial sex or to provide labor or services against their will.
