"Investigating the Link Between Gun Possession and Gun Assault"
After we adjusted for numerous confounding factors, gun possession by urban adults was associated with a significantly increased risk of being shot in an assault. On average, guns did not seem to protect those who possessed them from being shot in an assault. Although successful defensive gun uses can and do occur, the findings of this study do not support the perception that such successes are likely.
A few plausible mechanisms can be posited by which possession of a gun increases an individual's risk of gun assault. A gun may falsely empower its possessor to overreact, instigating and losing otherwise tractable conflicts with similarly armed persons. Along the same lines, individuals who are in possession of a gun may increase their risk of gun assault by entering dangerous environments that they would have normally avoided.58–60 Alternatively, an individual may bring a gun to an otherwise gun-free conflict only to have that gun wrested away and turned on them.
Another gun culture myth.
