Then it would be a case of it they did this (they wouldn't as it would cost too much) men would revert to only seeing girls who are well reviewed by punters who have reviewed other girls. That way they could be sure they were actually visiting a prossie. Its simple and there are simple ways around it
Plus even if the police knows a prossie works form a certain premises they cannot prove the men going in and out have had sex let alone paid for it. No prossie worth her salt is going to allow them access before hand to set up recording equipment (again they wouldn't do that anyway) so they would have no proof whatsoever of sex taking place let alone payment.
Again if the police harassed a girl for not grassing on her punters she could very easily put in a complaint and get the harassment stopped as it would be illegal for the police to harass a girl to get her to give evidence against someone. I for one would bloody well make a complaint and would go to the bloody papers too if they did that to me as I wouldn't put up with them banging on my door every few minutes. Its amazing what a complaint or two for harassment can do and they wouldn't be able to keep doing it as even the police are accountable for their actions in this country
Yes, but how it would probably work is that the police would find popular wg who advertise and surveil their premises and nab the punter as he goes in or leaves. Arrest on suspicion and then get you to confess and pay a fine or risk prosecution. If you want to play smart with them they will have your personal details/mobile/cctv/electronic data from ISP/ATM cash withdrawal etc. I believe this is how it works in Sweden. Most punters will pay the fine rather than take it to court.
As for the stuff about a police not being able to prove that a man was buying sex, that's just la la land thinking. A jury don't need to see pictures of a punter shagging a wg to believe on the preponderance of evidence presented that he went there to have sex or engaged in sexual activity for payment. Also, under the "Nordic Model" it's legal for a w/g to sell sex so the Police will ask her if she had sex with the man and she will of course say "yes" unless she herself wants to risk prosecution for no good reason.
Note, this is why the Nordic model is more "anti-punter" because in the US model both parties need to ensure they don't get caught to avoid prosecution and have mutual interest in complete discretion. The Nordic model criminalises one side so the police have a made snitch.
Whilst prosecutions are expensive you old need a few and some press releases to instill a bit of fear and that's all it's supposed to be a legal deterrent on the demand side.
