I would be happy to explain my understanding of the difference between the sections on procuring and those on trafficking.
They are connected, of course, but the big difference is in determining whether the victim is forced, in a number of ways, to engage in prostitution. The difference is whether it is her choice—a word that I do not like very much. Procuring is taking the profits, but not forcing the woman, by various means, to remain confined and to give him all her earnings. So there is a business relationship between the procurer and the victim.
In a case of trafficking, however, all the earnings are generally taken away and the girl or woman is forced to remain in one place, by physical or psychological means. It is not always a case of her being tied up.
That is where the difference lies. Trafficking is one level up. That is why they say that there is never any consent in trafficking situations. Clearly, the case can be made that consent is relative in prostitution cases, but it is all a question of degree.
