Nope, no agenda here - perfectly unbiased.
Hemenway is a long-time lefty activist.
Hemenway's work on guns and violence is a natural evolution of his research on injuries of various kinds, which he has pursued for decades. (In fact, it could be traced as far back as the 1960s, when, working for Ralph Nader, LL.B. '58, he investigated product safety as one of "Nader's Raiders.") Hemenway says he doesn't have a personal issue with guns; he has shot firearms, but found the experience "loud and dirty—and there's no exercise"—as opposed to the "paintball" survival games he enjoys, which involve not only shooting but "a lot of running." He also happens to live in a state with strong gun laws. "It's nice," he says, "to have raised my son in Massachusetts, where he is so much safer."
