Whose news?

Nick Davies has come in for a lot of stick lately for his book Flat Earth News, exposing the sloppiness of fellow journalists. Media workers against the war have come down on his side, but seem upset that the right are trying to 'co-opt' him on their side. They say of Davies:

Disgust with the “war on terror” runs right through this book. The anti-war movement must get behind its author.

Surely, it doesn't matter whose side Davies is on. He's either right or he isn't.
