Ms. Colvin, a Long Island native who was 56 when she was killed, was a star of the British press, known for dedication and pushing the limits of risk to tell the stories of civilians affected by war. She was less of a household name in the United States, but the court’s decision comes amid a wave of new attention to her life and death.She was played by Rosamund Pike in the recent feature film “A Private War,” and was the subject of a biography by a fellow journalist, Lindsey Hilsum, and a documentary by Paul Conroy, the photojournalist who was her longtime reporting partner. He was seriously wounded in the attack that killed Ms. Colvin and Remi Ochlik, a French photojournalist.
