The authors inadvertently omitted citations to the following publication: Koper C. Crime gun risk factors: buyer, seller, firearm, and transaction characteristics associated with gun trafficking and criminal gun use. 2007. Research Report to the National Institute of Justice, US Department of Justice. Philadelphia: Jerry Lee Center of Criminology, University of Pennsylvania. http://www.ncjrs.gov/pdffiles1/nij/grants/221074.pdf. This was a major study that we had intended to cite at several points in our article. We apologize to Dr. Koper and to readers of the Journal of Urban Health.
