Police officers are more likely to be raping victims, rather than safe-guarding them. And no amount of self righteous, sanctimonious posturing is going to alter that. You can bet those women were sending money back home, or paying off debts. Now what?
No- that is garbage. Notwithstanding rotten apples, Police are
not more likely to be abusers.
Whose hands then?
Exactly. By private citizens; charidees? Screened how and by whom, and with what assurances?
If the women are trafficked and working in 'chinese' parlours, then they're almost certainly foreign nationals brought here illegally - and, having failed to prevent their entry to the country in those circumstances, the correct next step for UK authorities is to return them to their home countries. We've neither the resources nor the moral obligation to make the exploited peoples of the world British citizens, and purport to grant them 'safety'.
It's incumbent on us, as punters, to avoid places or adverts which bear the likely hallmarks of trafficking (and, better still - to actively report suspicions we have) - and that includes avoiding nationalities and ethnicities that are a greatest risk of being trafficked.
