Glenn Greenwald has a great post that all reporters should read. It talks about the Samantha Power quote that got her in trouble, where she tried to retroactively make it off the record. The UK reporter refused, which riled some US reporters.
Greenwald scolds American journalists for their tendency to give the powerful in this country a pass, which is been very damaging. Here is a sample:
The number one rule of the standard establishment journalist is to avoid offending the powerful because the more offense they give, the fewer favors the powerful will do for the journalists. Conversely, and by logical necessity, the more journalists please the powerful, the more favors the powerful will do for them. As Carlson put it: "People don't talk to you when you go out of your way to hurt them as you did." I can't think of any single dynamic that better explains what has happened the last eight years than that one.
