Flash, bang, wallop - what a picture!

I'm a private sort of person, so up to a point I can empathise with the Duke and Duchess of Cambridge who are getting irritated with photographers stalking them looking for candid photographs of their children - specifically Prince George at the moment. But, through no particular fault of their own, they have to accept that they, and their children, are celebrities, and therefore fodder for that part of the media who deal with that sort of thing.  Annoying, yes, but it goes with the job. They claim that their main concern is protecting their children - but from what?  The whole point of these "candid" shots is that the quarry should be unaware of the fact that they are being photographed, so where's the harm to George, at least while he's still a little child? Like I say, I can understand their irritation, but it's part of being members of the Royal Family, and that isn't going to change, so they need to come to terms with it.
