I'm A Photographer, Not A Terrorist

Why is it when I go out and about with nothing more than a camera am I followed, distrusted and approached as if I am a criminal?


I went to a local shopping centre today with my wife and son, as normal I took my camera with me, my son went with my wife down a set of escalators I stood at the top waiting for him to come up and took the lens cap off to take his picture, as soon as I did I was approached by a "jobsworth" and told I could not take any pictures in the centre, I ask why and was told I could be a threat, I told him to go away, he did, I still took the shot.
