The chief must be a strong leader for both the police department and the neighborhoods facing violent crime. There must be a common commitment to reduce violence by everyone in the community—as well all police personnel who serve the community.

~Art Acevedo—Chief of Police, Houston, Texas, Police Department

Developed by the Bureau of Justice Assistance and the Major Cities Chiefs Association, this guide is intended to identify the critical elements of violent crime reduction efforts and to put before the law enforcement community a sample of the remarkable array of programs, services, and assistance available from the U.S. Department of Justice. This guide recognizes the complex challenges confronting today's law enforcement executives and offers ideas on how to approach the extraordinarily difficult problem of developing effective tactics and strategies to deal with those challenges.

To counter the continually growing and changing threat of violent extremism, the U.S. Department of Homeland Security (DHS) Science and Technology Directorate (S&T) has developed a free and publicly accessible research findings dashboard that hosts more than 1,500 catalogued research documents on terrorism prevention and countering violent extremism.  This dashboard is an agile, multidisciplinary knowledge‑based capability that helps to systematically develop a landscape of the existing research in this topic area across multiple disciplines, including social and behavioral science.

The National Counterintelligence and Security Center (NCSC) has developed an online Cyber Training Series designed to increase understanding of the broader categories of cyber-attacks.  It introduces specific terminology and real-world applications in three modules:

• Cyber Explore—Fundamentals of Cyber: Designed for professionals new to the cyber realm. 
• Cyber Aware—Anatomy of a Hack:  Designed to demonstrate to users where network and system vulnerabilities may be while helping them to understand common hacking methods.
• Cyber Exploits—Understand the Threat: Designed to increase understanding of the broader categories of cyber-attacks.  It introduces specific terminology and real-world applications so that users can recognize the threat when they see it.

In late September 2018, the Federal Bureau of Investigation (FBI) released the 2017 Crime Statistics.  After two consecutive years of increases, the estimated number of violent crimes in the nation decreased 0.2 percent in 2017 when compared with 2016 data. Property crimes dropped 3.0 percent, marking the 15th consecutive year that the collective estimates for these offenses declined.

The Crime Data Explorer (CDE) is an interactive online tool that enables law enforcement, media representatives, academia, and the public to easily search for and find data from the FBI's Uniform Crime Reporting (UCR) system.

The Law Enforcement Advancing Data and Science (LEADS) Program develops the research capacity of midcareer law enforcement personnel who are committed to advancing and integrating science into law enforcement policies and practice. 

The National Institute of Justice developed the LEADS Strategic Plan for 2016–2013 to describe its current and projected efforts to increase the use of evidence and science in law enforcement and to support practitioner-led research.  This document will be of interest to researchers (academia, government, and law enforcement); federal, state, and local government partners; and stakeholders in the justice system.
