The written tone and the spoken tone change and the reporters' disbelief in the veracity of the government spreads to the readers and the viewers.

The relationship between press and politician - protected by the Constitution and designed to be happily adversarial - becomes sour, raw and confrontational.

The ethics of editorial judgement, however, began to go though a sea change during the late 1970s and 80s when the Carter and Reagan Administrations de-regulated the television industry.

Given what the media have put the country through this past decade, it must come as a surprise to most Americans that the press has a code of ethics.

Journalists, who are skeptical to begin with, simply do not like to be lied to or made fools of.

Most journalists now believe that a person's privacy zone gets smaller and smaller as the person becomes more and more powerful.
