The photographer kept taking pictures after Bjork's companion asked him not to.
IN ADDITION, if he had bothered to do any research into his subject, he would have discovered the fact that she attacked a reporter years ago in a similar situation, after photographers kept taking pictures of her with her child leaving an airport.
Not to justify Bjork's attacking the photographer, but he should have known exactly what he was getting into.
That's terrible. If you're famous you have it coming to you. You don't have a life, you have to sacrifice privacy and your image needs to be on display constantly, regardless if you don't want it to. That's the price you be for being a celebrity.
