That's pimps and organizations, whether it be through organized crime and/or other means.
Getting back to the victim, in most cases the first point of contact is with the police through some form of violence, normally always in cases of a form of violence, and a lot of them are in a position where, if they are under the control of a pimp or a person in authority, they feel very compelled not to speak to the police through more threats of violence.
Would you agree with that statement?
