When news broke earlier this month that two Associated Press journalists were attacked in Afghanistan, a familiar feeling of loss and powerlessness immediately took hold of me. Anja Niedringhaus and Kathy Gannon were sitting in a car when an Afghan police officer fired on them. While I never had the fortune to know Anja, who was killed instantly, Kathy has filled an important role in my life for two decades, since my mother, a foreign correspondent with the AP, was killed when the helicopter she was riding in crashed into a mountainside in Afghanistan.
