Aha, I've seen that study on Hacker News before and I wrote a variant of the following observation:
A charitable read of that paper, particularly p. 25, would suggest that trafficking dropped from 19,740 cases to 12,350 cases when prostitution was liberalised.
I've done enough statistics to say that I don't think the paper conclusively shows evidence of a problem; particularly given how hard it must be to gather data on illegal things. Need more rigour to be used for this sort of discussion although it does show that there is a risk to be considered.
