I was watching The Colbert Report the other night when a picture of my local mosque flashed across the screen. Colbert was covering a story that the Murdoch-owned New York Post had broken a few days earlier: a man had barged into the mosque during a service, cursed at the congregants, pissed on their prayer rugs. 'No one can pray now,' someone had told the paper. 'The rugs are completely soiled. It was disgusting.' So far, so bad. But Colbert (who isn't a journalist) didn't know that the Post journalists (it had taken three of them to file the 168-word story) had got it almost entirely wrong.
