it is very difficult I think for people to accept what a serious problem sexual assault is. figures in Britain and the US put it at anything between one in six and one in four women. continuing the facebook debate somebody said to me 'that can't be right, that would mean on average 119,000 rapes in Britain every year.' yes. yes it does. there will be an estimated 85,000 rapes in England and Wales this year according to rape crisis UK.
