Many pro's go to the police because they've been abused one way or another to be 'ignored' by the police. They pull them in and charge them only so they have to move into more darker secluded areas to avoid being caught by the police, so therefore putting themselves in much more higher risk.

I think it's difficult to say why they do it, it's not for us to judge. Until you are / been in that kind of position yourself then speculation is just that.
