Police report into brothels dismissed as "amateurish"

There is a debate about sex trafficking. It is certain that there is a sex industry. What is less certain is the degree of trafficking involved. There are those who argue that all prostitutes are victims and those who argue that there are prostitutes who are free independent women, choosing to sell sexual services. Quantitative research? Of course there isnt! All evidence so far is anecdotal at best. In truth, we don't know. But it's about time we found out! What's the evidence from the Netherlands and Sweden?
