I would suggest that it depends on your framework for objectivity as to whether it is possible or not. If one takes what I believe to be the strict sense of it, as a view of reality with no perspective applied to it, then I think that is a false, impossible notion. If one qualifies their objectivity as 'objective within a subjective, present notion of humanity / reality' then it seems a reasonable and useful tool for laying out what one believes to be the factual data of a situation that others would be able to perceive and interpret as they wish.
