Not more bans

Bansturbation, or perhaps its opposite; masturbation by government decree. The Harriet Harman wants to ban paying for sex. Congratulations this has to be pretty well the most ridiculous law out, I can see it now in a seedy bar somewhere downtown a haft cut guy slides up to girl by the bar:
"You look fantastic," he slurs, "Fancy me getting you a drink then?"
"Not at all love," she replies, "I'm an undercover cop and your nicked for trying to buy sex. I just need a couple more and I've got my quota."
"Handcuffs already? Fantastic, and we only just met!"

This isn't going to make prostitution go away, it will just push it further underground where the women that sell sex will be in even greater danger. It will not make people trafficking for sex go away, it will just mean that the traffickers will treat their women even worse in order to make more money so as to offset the risks that they are taking. If they really wanted to help prostitutes then they would be trying to get them to work out in the open where they would be in less danger, both physical danger and of exploitation.

One of the earliest examples of a knee jerk ban from this government was the ban on hand guns. They logic was simple. Stop people being able to legally get guns and they would not be able to get guns, ergo less people would be killed with them. The result was rather different; the number of gun deaths got steadily worse because if you are already that far removed from social constraint that you are willing to kill possession of an illegal firearm isn't really that big a deal. Exactly as was predicted the ban on guns had a bad effect on those that used to use their weapons carefully and peacefully while having precisely no effect what so ever on the criminals who would use their (normally already illegal) weapons to harm others.
