Wow that's totally sick. It's not easy for me to understand why the legal system attacks the ones it's supposed to help, I mean, makes selling illegal, rather than making only buying illegal. (In some/many? countries in Europe, it's ok to sell sex, but illegal to buy. So the prostitute can go to the police)
