Prevention Matters

In a first-of its-kind study, epidemiologists at the University of Pennsylvania School of Medicine found that, on average, guns did not protect those who possessed them from being shot in an assault. In fact, the study estimated that people with a gun were 4.5 times more likely to be shot in an assault than those not possessing a gun. The study was released online this month in the American Journal of Public Health, in advance of print publication in November 2009.
