Simon Chapman, Philip Alpers, Kingsley Agho and Mike Jones have a new paper out today, looking at the effect ofÂ the 1996 gun law reforms on mass shootings. Like the Baker and McPhedran paper (whose homicide and suicide findingsÂ I blogged on), Chapman et al use time series data on homicide and suicide from 1979-2003, and compare trends in the pre-reform and post-reform periods.
I’m still trying to figure out some of the details of the paper (eg. I’m puzzled as to why the focus is on the impact of the buyback on the trend in the rate rather than the level of the rate). But meanwhile, I’ve posted below the key graph from the paper. If it’s not large enough, the full paper is online here.
