To say it’s been a bad week in the business of journalism would be something of an understatement. Brian Williams has been suspended for lying about his experiences reporting from Katrina and the Iraq War. Jon Stewart is stepping down from the Daily Show desk, which is going to be a painful end of an era for many people. And just in the last day, two stalwarts of the industry have died suddenly: Bob Simon in a car crash and David Carr, who collapsed yesterday in the New York Times offices. Carr I remember most for this excerpt from his memoir, a harrowing look at his time as a junkie. But, because much of this time is lost in his memory, he reported on his own life, going back and talking to the people who knew him during this period. It’s a long piece, but so worth the read.
