One factor is publicity.
How many ranters go on TV at all hours including peak viewing to say prostitution is evil and, with utterly false logic after getting the emotional attention, offer their support for dangerous legislation?

How many intelligent persons go on TV at any time to outline the facts, say look, paying prostitutes for sex is not the highest thing in all possible worlds but it should be managed with safety and respect for the individuals concerned unless crimes are being committed.

Public consultation serves a 'great' function (at least on paper): it allows politicians to say "We held a public consultation." (and then went ahead and believed what we wanted to believe)
(and if anybody counts the responses, they will quote an
ad populam excuse that 5 thousand, or however many self-righteous and well-organised bible-bashing minority loudmouths, were "in favour" but they only received 50 against, and most of those were anonymous.

End of story on the ground is that police forces, who have considerable discretion, can use their perception of public sentiment to harass prostitutes, their clientele, their working places.
Look, I love the police, they are trying to do their job. And so are most politicians. Cramming legislation or media slots with so much information that travesties of justice go unnoticed is a popular technique. Hopefully someone will take a step back and look at everything calmly before such travesties are rubber-stamped.
