I agree that the police and courts were following the current law. But some aspects of the current law are poor. If the police and courts everywhere followed the law to the greatest extent possible, it would be much more difficult to punt in this country. Potentially no London agencies, no sex parties ... perhaps even a MFF in-call would be difficult (two escorts=brothel?). Not suggesting there is any likelihood of the laws easing. If anything, we hear the opposite: occasional whispers of the NI model being extended.
I hope that the status quo lasts for now. Any attempt to change would likely backfire. And anyway, this particular pimp sounds like a bad guy, so I don't mind he is in jail.
