I was slighly horrified to read Nick Davies (a journalist I normally have a lot of respect for, and consider his book Dark Heart to be mandatory reading) article in the Graudiad yesterday, which contained the elemetary error that just because a six month operation had failed to successfully prosecute anyone for sex trafficking in the UK, the problem wasn't that bad. Here is an excellent rebuttal to that piece, also from the Grauniad (which itself contains a link to Mr Davies original piece at the top, which is why I haven't linked it here.)
