Countering Mass Shootings in the U.S.
Tuesday, September 17, 2019  10:00am – 12:15pm
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.

Long Term Recovery of Communities Following Mass Violence Incidents

The University of Oregon Police Department and the California Victim Compensation Board are pleased to announce the Leave No Victim Behind IV national training conference for 2019. The conference will take place on October 21-23, 2019 at the Conference Center of Las Vegas. The Leave No Victim Behind conference series will continue its focus on best practices for responding to mass violence and unique partnerships between law enforcement and victim services to assist victims of crime.

This year’s conference theme is long term recovery of communities following mass violence incidents. The conference dates follow the second anniversary of the Route 91 Harvest Festival shooting in Las Vegas on October 1. Las Vegas was specifically selected as the conference location to allow participants the opportunity to observe how a community continues to meet the needs of victims, survivors and responders of a large-scale mass violence incident on a long term basis. Participants will hear from responders and victims of the Las Vegas Route 91 Harvest Festival regarding their recovery process over the last two years.

Conference sessions will include presentations on long term recovery from responders and victims of the Virginia Tech shooting, the bombing of Pan Am Flight #103 over Lockerbie, Scotland, the Boston Marathon bombing, and more recent incidents such as the Borderline Bar shooting in Thousand Oaks, CA. Speakers will share best practices, challenges and their personal experiences.

The conference agenda will also feature a panel of survivors of law enforcement officers who have lost their lives in the line of duty. Sadly, the nation has witnessed a discouraging trend in law enforcement deaths and communities are seeking assistance with responding to and coping with the aftermath.

Information regarding resources and technical assistance provided by the federal Office for Victims of Crime, school grants and non-profit organizations will also be presented.

Conference attendees will include law enforcement, victim service providers, first responders, community based organizations, campus officials, crisis response teams, emergency management professionals and behavioral health specialists. This year’s conference is the fourth installment in the Leave No Victim Behind series and will build upon the excellence demonstrated in our prior conferences, which in the past have been supported by our local, state and federal partners, including the federal Office for Victims of Crime and the Oregon Department of Justice.

This one of a kind gathering of experts and responders provides essential training for the multiple professions that help victims and communities recover and heal from mass violence incidents. In addition, the conference provides opportunities for networking, information sharing and collaboration. Our non-traditional approach to adult learning will include a remarkable venue, excellent conference provided meals and an exceptional line up of subject matter experts.
