The U.S. economy depends on the quick and efficient flow of millions of tons of cargo each day throughout the global supply chain. However, U.S.- bound vessels and maritime cargo shipments are vulnerable to criminal activity or terrorist attacks that could disrupt operations and limit global economic growth and productivity. The James M. Inhofe National Defense Authorization Act for Fiscal Year 2023 includes a provision for GAO to assess federal efforts to secure U.S.-bound vessels and maritime cargo from national security-related risks. This report addresses (1) how DHS secures these vessels and cargo from supply chain risks, (2) the extent that DHS used selected leading collaboration practices, and (3) the extent that DHS assessed its approach. GAO reviewed agency policies, procedures, and collaboration efforts and government-wide strategy documents, and assessed DHS collaboration efforts against five relevant leading practices identified in prior GAO work. GAO also interviewed Coast Guard and CBP officials from 16 field locations at a non-generalizable sample of eight U.S. seaports selected for varying volumes of cargo and diversity of geographic regions. What GAO Recommends GAO recommends that the Coast Guard, with sector partners, develop objective, measurable, and quantifiable performance goals and measures and use this performance information to assess progress towards the goals and effectiveness of the layered approach to securing vessels and maritime cargo on an ongoing basis. DHS concurred with our recommendations.

This document, Threat Assessment in Schools: A Guide to Managing Threatening Situations and to Creating Safe School Climates, takes these findings one step further by setting forth a process for identifying, assessing, and managing students who may pose a threat of targeted violence in schools. This process–known as threat assessment–was first pioneered by the U.S. Secret Service as a mechanism for investigating threats against the president of the United States and other protected officials. The Secret Service threat assessment approach was developed based upon findings from an earlier Secret Service study on assassinations and attacks of public officials and public figures.

This report documents representative case studies of incidents in which targeted violence was thwarted by the actions of college students, school administrators and faculty, campus police, and other stakeholders. The examination of these case studies and the lessons learned from them demonstrates progress toward increased safety at colleges and universities. In addition, a companion publication entitled School Resource Officers: Averted School Violence Special Report presents information on K–12 averted violence incidents and the role school resource officers (SRO) assume in supporting student safety.

Forming part of the Prevention Project, this paper examines the effectiveness of mentorship interventions.

Mentorships, as interventions targeted at the specific needs of individuals or groups of individuals and adapted to the local environment, are assumed to have a higher chance of tackling violent extremism than broad approaches targeting general populations. This paper demonstrates that evaluations of mentorship interventions are limited in number and scope – as with the wider P/CVE field. Existing evaluations often lack well-developed theories of change and are over-reliant on anecdotal evidence. It is therefore difficult to draw causal links between mentoring and positive P/CVE outcomes. This paper is, however, cautiously optimistic about the effectiveness of mentorship programmes.

For mentorship programmes to be successful, stakeholders with a thorough understanding of the target group’s social setting and context are crucial. Connections to local material and human resources and services are important for programme effectiveness and sustainability.
