Marcus: For most ethical dilemmas the journalist is likely to face, traditional journalistic ethics is clear, adequate, and essentially correct. For example, when journalists have uncovered newsworthy information, they should go to press with it as soon as possible. No delay motivated by the journalists' personal or professional interests is permissible. Anita: Well, Marcus, of course interesting and important information should be brought before the public -- that is a journalist' s job. But in the typical case, where a journalist has some information but is in a quandary about whether it is yet important or newsworthy,  this guidance is inadequate.
The point made by Anita's statements is that there are common situations in which a journalist must make a decision and in which no principle of journalistic ethics can be of help.
