For people who ask questions for a living, reporters are shockingly defensive when the tables are turned. I’ve found they are generally reluctant to correct their errors or engage critics on substance. That’s why it’s so encouraging to see this McClatchy column. It uses a debate with critics of its reporting on casualties in Iraq as a jumping-off point to help readers decode a frequently arcane debate — really excellent stuff and a model for what I hope journalism will look like in the future.
