Bill Moyers attacks
Bill Moyers said that Tomlinson (Chairman of Corporation for Public Broadcasting) should not attack or impugn individual shows.

Journalists owe us the right to judge what thought processes and values that color their observations. So we can judge to see if the author is seeing the same thing we as readers see.
