Policing and Crime Bill

I apologise for failing to convince anybody with my previous example. I shall try it again. You have customers for the prostitutes; you have eastern European—we will say eastern European, but they could be from any part of the world—prostitutes who are moving between cities. The police gather evidence and raid the establishment after observing who has come and who has gone. They will make criminal charges against the traffickers and the brothel owners, but the customers will have committed an offence if it turns out that the prostitutes were trafficked because under strict liability legislation customers will be liable whether they knew that the person was trafficked or not.
