In UK there has been a certain amount of unwanted attention attracted by 'real' cameras including film and digital SLR's. Some people who don't know any better automatically assume that you are either press or someone with a tendancy towards taking images of children to post on the web for pedophiles to savour, or on the other hand you are somehow connected with a terrorist organisation gathering information for the next attack. (It has never actually happened to me)

Both way, way, over the top in their assumptions, it is just plain unconnected thinking 'cos a camera-phone would be a far more effective tool and attract less attention
