On another issue, I spent yesterday with some women who were organising and sorting clothes for the Syrian camps.
They also organise knitted items in which they sew a message in Arabic and Kurdish, along the lines of 'made with love and friendship just for you by xxx in the UK'
They were, as are many women, discussing the implications of Cologne.
It occurred to me that, having just sent a load of men's clothes to a refugee distribution centre, that a trick may have been missed.
Some attackers had crib sheets "I fuck you, I kiss you, etc."
What about putting, in every pocket of every pair of jeans, jacket, shirt, a paper with a message too.
Thinking on the hoof and train here but something that spells out we are very happy to welcome this who respect and accept our culture and way of life, that women are equal in our society (we could ask the Belgians and Norwegians for experience in the messages they have used) and if we even have one young person pause for thought, or become aware of the legal/deportation/penal consequences of sexual crimes, then it will be a start.
