A new paper by doctoral candidate Nicole Johnson and Professor Caterina Roman, both in the College of Liberal Arts’ Criminal Justice Department, seeks to offer some of the missing context behind Philadelphia’s gun violence crisis. The study shows that from March 2020 through June 2021, gun violence went up on average by 21.6% each two-month period, albeit slowing down considerably in 2021. The areas that saw increasingly more gun violence had something in common: they had high drug market activity.
