It really is difficult to know which is the worst bit of this

As an adjunct to the story about circumcision and HIV risk - I've done a small bit on why this is mostly crap, but ask if you want more - in the Metro today was a paragraph or two:

Legalising prostitution would reduce the spead of sex diseases by half... Regular testing of sex workers would halt a dramatic rise in HIV cases in Britain. About 70 per cent of all STIs occur amongst prostitutes and their clients, a BMA study revealed.

Crap, dangerous crap, and even more dangerous crap.

It turns out that the longer version is here, and it has new levels of crap itself.

Incredibly, the source of the speech - not study - is Chris Spencer Jones, chair of the BMA public health committee.
