I don't understand the whole notion of 'raiding' these parlours unless there is clear evidence that women are being 'trafficked' from the EU and other countries. My nearest 'parlour', Manyana in Selly Oak has been operating for years. It now has a discreet entrance to the rear, and on the face of it, looks like an 'adult' bookshop from the front, close to a bus stop. Selly Oak also has a number of other brothels, 'First Class' and 'Pennys' that have also been open for many years and are right in the heart of University locations. Aren't they licensed with the City Council? Perhaps they, in some agreement with the police allow them to operate within certain criteria. I've no idea what that criteria is, but I do deplore the idea of women being forced into prostitution by traffickers and/or vile, controlling pimps. If this is the case I would fully endorse any raid on the premises.
