Countering Mass Shootings in the U.S.

Dirksen Senate Office Building, Room SD-106, U.S. Capitol, Washington DC

Mass shootings have unfortunately become an all too common occurrence in the United States, claiming thousands of victims killed or injured in the last decade alone. Mass public attacks in particular appear to have increased in regularity and severity, leading to a heightened sense of national fear and insecurity. Addressing this urgent problem requires evidence-based policy responses based on careful analysis and evaluation. To respond to this need, George Mason University’s Center for Evidence-Based Crime Policy and Carnegie Mellon University’s Heinz College, with the support of the Harry Frank Guggenheim Foundation, have organized a congressional briefing to bring the most up-to-date research on the subject to the U.S. Capitol. Registration is free but required for this event, as space is limited.


All papers from this project (including those below) will be published in Criminology & Public Policy in February, 2020.
