From today, if the police catch you with a camera in a public place taking a photograph, you will at best be stopped and questioned under anti-terrorist legislation and at worst will be arrested, thrown into a cell and your camera and / or images damaged or destroyed.
There is only one answer to this outrageous affront to innocent activity; guerrilla photography.
From our office windows, or using telephoto lenses, or over a busy road across which they can't run, today is the day we start snatching shots of policemen. It will be a snap and run campaign - one shot, then merge into dense crowds, or duck into a department store.
I have no doubt that the native wit and ingenuity of the British people will produce before long a magnificent crop of forbidden photographs and shame this useless law into desuetude.
