It’s no surprise that journalism can be dangerous work. Reporters are routinely killed on assignment in conflict areas or covering other hazardous parts of the world. But what about those killed not in the course of their work but because of their work?

Like 54-year-old Philip Agustin, whose newspaper was about to publish a special edition on missing government funds in the Philippines when he was shot in the back of the head at his daughter’s home on May 10, 2005. Or Bautista Merino, 24, and Martínez Sánchez, 20, the hosts of a local radio station in Mexico’s tumultuous southern state of Oaxaca, who were driving home on a rural highway on April 7, 2008, when they were gunned down by unidentified assailants wielding assault rifles. Or Mahad Ahmed Elmi, a Somali morning talk show host shot dead outside the entrance of his radio station’s building as he arrived for work on Aug. 11, 2007. Later that day Elmi’s colleague Ali Iman Sharmarke was killed by a remote-controlled bomb that detonated under his car as he was returning from Elmi’s funeral.
