Yet somehow these "slaves" never escape when out being hookers.
Somehow they never escape from vehicles or from houses with windows and doors.
The lack of motivation among these "slaves" is appalling.
Many of them are far away from home and scared, and see their "masters" as holding all of the cards. It's like the cover ups in the Catholic Church and Penn State. Just because it took a long time to out the bad guys, that doesn't mean the victims wanted to be abused.
