I don't want to comment on something I'm not an expert on. My research area is sex work, not human trafficking.
However, I am not sure that increasing these penalties has really improved the situation of victims of human trafficking. I also want to mention that legislation that puts sex workers at risk does not help victims of sexual exploitation or victims of human trafficking, because it puts everyone at risk.
I think we need to think about this and perhaps use the excellent Canadian studies that have been done on the subject to find solutions that could help the victims of sexual exploitation and human trafficking. We must indeed help them, but without endangering the sex workers who are in this industry and who have the right to live off it.
