I am going to call the cops on this really young prostitute here.
Before calling the cops, just understand that it may better to try and help the young prostitute out instead.
I've seen the her around for years, she was a loser when she was younger.
I understand you find this person offensive, but sex workers need social and psychological support, not jail. If you want to do something, you should encourage to meet with a social worker.
I don't care! She needs to be stopped.
I understand your point of view, but I think that there are better ways to handle the situation than calling the police. Just because she is a sex-worker does not mean she is a bad person, and in some places sex-work is completely legal. I really think you should try to get her to meet with a social worker or someone else who can help her onto a better path.
