> "Denmark, which decriminalised prostitution in 1999 – the same year Sweden made the purchase of sex illegal - has four times the number of trafficking victims than its neighbour despite having around half the population." That's not very strong evidence. It could easily be that the sex industry in Denmark was thriving pre-1999 and floundering in Sweden (with policy choices & trafficking as results). Better proof would be comparing the growth rates in trafficking between two countries with similar base rates, where one legalized and one didn't. Intuitively, I hope you can understand why many people think legalization can be a great tool for combatting trafficking. By doing so, you move the sex trade out into the open and away from gangs/criminal syndicates and allow for regulations which can serve public health & anti-slavery purposes.
