It seems widely accepted that there are different degrees of justification for the invasion of privacy, depending on the position you hold in the public eye. Firstly there are people who hold a position of power and responsibility, ranging from national power (e.g. politicians) to local responsibility (e.g. teachers and clergymen). Secondly, there are celebrities; people who choose to be in the public eye but not because they hold a position of responsibility. The third group is ‘regular’ people, who are thrust into the spotlight through a famous relative or by an event or disaster that they were part of or witnessed.
