In the BBC report there was a quote from the mall saying they ban photography in order to protect the privacy rights of shoppers.
Meanwhile every section of the mall is covered by CCTV and every store likely has extensive CCTV too, sometimes even in places like change rooms. I find their concern about shopper's privacy touching, but hollow and insincere.
What is doubly annoying, as reported in the BBC story, is that the photog was originally reported to mall security by the staff of the ice cream shop where he had bought the icecream for his daughter:
Quote: Staff at an ice cream stall in Braehead became suspicious after they saw a male shopper taking photographs at their counter.
"The staff thought the man had also been taking photographs of them and they alerted one of the centre's security staff."
They were worried that they were being photographed, as much as being concerned about the kid. So more general paranoia about photography.
Meanwhile most of the staff probably have no qualms about putting up on Facebook all their family snaps and exposing them to the world, nor any qualms about being videoed 8 hours a day by CCTV whilst at work, and out on the street, and in the pub, and in the supermarket.
