SC, you don't need to justify escorts to me, I'm just as involved there as anyone. My point is that we are not bystanders, we are involved, and as a result, can't claim to have nothing to do with it.
I mean really, if you have sex with a woman who, as it turns out, did not really consent to have sex with you, can you honestly say you play no role??? We ARE talking about non-consensual sex here. The word usually applied to that is rape.
Yes, you had many reasons to believe that she consented, so I doubt it cuts it as rape under the criminal code. On the other hand often the legal expectation is explicit confirmation of consent, not just assume it. Are you sure you've done everything reasonable to ensure consent??? If there's anything suspicious and you DON'T ask, just say it's not your problem, well, getting pretty close to actual legal rape at that point. If you have GOOD reason to suspect that she is being forced into having working as an escort and you have sex with her at that point it IS rape, legally and morally.
You have a moral duty, very possibly a legal duty, to make sure your escort that you are about to have sex with consents.
Second, it's not just that you are involved--it's also that you are very likely the ONLY person in a position to offer help. If she is cut off from everyone other than her abusers and her customers then you, her customer, are it in terms of people who can do anything about it.
Just saying "it's a police problem, none of my business" is lame. The police need the support of the community to do a good job, and that's you. That reaction is just like the guys in bad areas who see a crime and then refuse to co-operate with the police. Same lame excuse. Same lame result.
"That's about all i can do to help out" is a cop out, it's not all you can do, it's not all you have a duty to do.
