But if a client is criminalised, he may be fearful of the police searching a worker’s phone or apartment and identifying him. As a result, he refuses to give basic screening information like his real name, and switches to calling from a hidden number. A man who wants to carry out an assault or robbery will know he can arrange a meeting with a sex worker and be virtually untraceable; the criminalisation of clients gives him leverage to refuse to make himself identifiable.
