there is a simple workaround for the whole calling the cop plot-hole in the story, he could make it :
1. The brother/father make it so that if she ever tries to call 'em they will paint it as if she was dealing with prostitution and/or deals with illegal substances as well
2. Make it so that the father might be a cop and can threaten her not to call anyone
3. Instead of calling cops directly she might decide to call a relative to the family she knows is a cop and .....(don't need to paint the picture here I think)
these are but only some simple ways to remedy the plot holes with the cop issue. I'm sure there are many other ways to fix it but again it's up to the dev's choice at the end of the day
