  Background Safe Streets Baltimore (Safe Streets) is a community violence intervention (CVI) program designed to reduce gun violence in neighborhoods with high levels of gun violence. Frontline workers are recruited for their ability to connect with individuals at highest risk for involvement in gun violence and mediate disputes, promote nonviolent norms for settling disputes, and connect program participants to services. Baltimore has fully implemented the program in 11 neighborhoods between 2007 and 2021. Six of these sites have been fully operational for less than three years and have not been previously evaluated. Prior evaluations of Safe Streets have shown mixed results across the sites and over time. Study Methods To estimate program effects, we analyzed variation in neighborhood-level monthly counts of homicides and nonfatal shootings for the period January 1, 2003 through July 31, 2022. The primary analyses were augmented synthetic control models for each site. This method generated a “synthetic” comparison for each Safe Streets site using a weighted combination of data from neighborhoods that did not implement the program but had similar levels and trends of violence before program implementation. We calculated program effects comparing treated sites to their synthetic controls, estimating what would have happened if Safe Streets had not been implemented. Because confidence in forecasts from statistical models tends to decrease over long periods of time, we generated estimates for the first four years of program implementation for the longer running sites in addition to estimates of the entire time a Safe Streets site has been in operation. We calculated average effects across all sites and within strata of site tenure (longer running and new sites) weighted by the precision of each site’s estimated effects. Key Findings: During the first four years of program implementation across the five longer-running sites, Safe Streets was associated with a statistically significant average reduction in homicides of 32%. Over the entire study period among these longer-running sites, homicides were 22% lower than forecasted if the program had not been implemented. Three of the five sites had significant reductions ranging from 28% in McElderry Park to 48% in Lower Park Heights. In SandtownWinchester, Safe Streets implementation was associated with a significant increase in homicides. Estimates of Safe Streets effects across the six new sites varied with an average reduction of 8% that was not statistically significant. Over the entire study period across all sites, Safe Streets was associated with a statistically significant 23% reduction in nonfatal shootings. Eight of the 11 sites had program-related reductions in nonfatal shootings. Four sites had significant reductions ranging from 29% in Lower Park Heights to 84% in Franklin Square. Sandtown-Winchester’s site was associated with a 53% reduction in nonfatal shootings over a period of more than seven years

This report is the product of the Reducing Violence, Building Trust: Data to Guide Gun Law Enforcement in Baltimore project. Researchers from the Johns Hopkins Center for Gun Policy and Research (JHCGPR) collected and analyzed data relevant to the enforcement of laws restricting the possession of firearms by prohibited individuals and unlawful carrying of concealed firearms to provide data-driven recommendations for more fair and effective practices. The project was designed to help inform the response to the dual crises in Baltimore—extraordinarily high rates of gun violence, and gun law enforcement practices that, in some cases, have violated the law and more generally weakened community members’ trust in the police. In 2017, Baltimore experienced its highest homicide rate on record during two out of the past three years and had the highest murder rate among cities with a population greater than 500,000 in the U.S.1 Homicides declined in 2018, but in 2019, Baltimore’s per capita homicide rate eclipsed the 2017 record, ending the year with 348 total homicides (58.6 per 100,000 population). Nine out of 10 homicides (291) in the city were committed with firearms. The number of nonfatal shootings in 2019, 771, was also higher than that seen in the past five years.2 Because illegal gun possession is often a precursor to shootings, making arrests for illegal gun possession has long played a prominent role in the Baltimore Police Department’s strategy to combat violent crime. While BPD arrests for drug-related crimes have plummeted by 70% from 2014 to 2019, arrests for weapons violations, principally illegal possession of firearms, have changed relatively little during that time period. Police units focused on illegal gun carrying in hot spots for shootings have helped to reduce shootings, but less focused enforcement practices have not always translated into measurable reductions in violence.3 Past efforts to get illegal guns off the streets and deter illegal gun possession without adequate oversight enabled civil rights violations, facilitated alarming criminal activity by BPD’s Gun Trace Task Force, and increased distrust of the police in many communities. These practices and their aftermath have lasting and harmful implications for public safety and justice. They also motivate current efforts by BDP to facilitate reforms and build trust with community members in compliance with the Consent Decree. Researchers from JHCGPR drew from a variety of sources of data from Baltimore and studies from other cities to summarize key findings concerning proactive gun law enforcement practices—legal issues, impacts of police stops and searches on individuals, impacts on gun violence, community members’ views on the appropriateness of police practices and their desire for greater police accountability, and measures some law enforcement agencies are taking to improve the effectiveness and prevent abuses from proactive gun law enforcement. The report cites prior systematic and expert reviews of relevant research, especially the 2018 report by the National Academies of Sciences, Engineering, and Medicine’s committee on proactive policing.a Several sources of data from Baltimore were used, including: 1) findings from a recent JHCGPR report on the effects of law enforcement and city-led strategies on gun violence (2,3) the United States Department of Justice’s City of Baltimore Consent Decree and reports from the selected Independent Monitor;  3) new data from court records on case dispositions for cases involving charges for illegal firearm possession; and 4) household surveys and focus group interviews with residents living in some of Baltimore’s neighborhoods most impacted by gun violence. The JHCGPR study team sought to identify promising models for effective and fair proactive gun law enforcement through interviews with law enforcement officials in 24 other jurisdictions. This report provides 13 specific research findings relevant to eight recommendations informed by evidence that is intended to guide future proactive gun law enforcement efforts capable of reducing crime and enhancing community confidence and trust.

With the rising threat of active shooters, armed off-duty and retired law enforcement officers may prove to be an effective tool in American homeland security. Yet, while the number of active shooter and critical incidents in the United States have continued to rise, the number of non-traditional response interventions has remained minimal. Unfortunately, the presence of armed, off-duty law enforcement officers can create other problems, often referred to as blue-on-blue encounters. This thesis examines the questions Can tools such as Hero911 mitigate some of the major risks associated with self-dispatch How can off-duty or plainclothes officers be best incorporated into active shooter response Finally, what processes can make utilization of non-traditional responders safer for all This thesis concludes that over the past 20 years of active shooter responses, first responders have missed an opportunity with respect to the use of non-traditional responders. On- or off-duty non-traditional responders serve as a force multiplier, which widens the pool of available responders. Use of any technology is not without risks, and to avoid more confusion during an active shooter event, training is paramount. Properly used, tools such as Hero911 can reduce the risks involved in non-traditional officer response.

Decades ago, carrying a gun—especially a concealed gun—was a reliable indicator of criminal activity in much of the country. Police officers who noticed a civilian “packing” were justified in assuming that the individual was thereby breaking the law; in short, he was an armed criminal. Under a key 1968 Supreme Court decision, this was reason enough to both stop and frisk the suspect.

Things have changed. Over the past several decades, most states have radically liberalized their gun-carrying laws, first by granting concealed-carry permits on a “shall-issue” basis, which means that anyone who meets certain requirements, such as training and a clean background check, is entitled to a permit. Now, more than 20 states no longer require a permit at all. And in June 2022, the Supreme Court, in New York State Rifle & Pistol Ass’n, Inc. v. Bruen, held that all states must allow law-abiding citizens to carry guns, invalidating New York’s requirement that applicants for a carry license must show a special need to carry, beyond the basic desire for self-defense.

Particularly during a time in which cities across the country have experienced rising gun violence, the court’s decision raises certain issues that need to be resolved. Chief among them: How can police continue to get illegally possessed guns off the street when it is legal—and, indeed, a constitutional right—for many individuals to carry guns on the street?

This report summarizes the legal landscape surrounding stops and frisks. It also investigates—using data from New York City’s stop-and-frisk program—how pedestrian stops of armed individuals tend to play out in practice. The goal here is not to take stances on guns or policing practices. Instead, it is to map out the legal status quo, highlight the tensions among competing priorities, and lay out options that judges and states with different sets of values might consider.

From the introduction: The need for a Handbook of Terrorism Prevention and Preparedness needs little explanation in the light of the fact that the dominant approach of counterterrorism, based largely on heavy-handed military action, has been such a failure - especially in the Middle East. The traditional military instrument of deterrence has not worked against enemies who have, in most cases, no fixed territorial basis while claiming to love death more than life. The decapitation of terrorist organizations by killing their leaders in drone strikes has created martyrs rather than broken their organization’s will to fight. The collateral damage of military strikes has often turned family members, friends and other witnesses near and far into avengers. For many societies, the “cure” of militarized counterterrorism has been worse than the “disease” of terrorism.

From the Introduction: While “terrorism” is one of the most widely used terms in adversarial political discourse, there is still no international consensus about its exact meaning.1 The discussion about the definition of terrorism has been going on for more than half a century and has led to a large number of publications (see bibliography at the end). The purpose of this article is to revisit and review some conceptual approaches in academia, government and international organisations to enable the reader to familiarise her-/himself with the current state of affairs, building on, and expanding, some of the author’s previous conceptual work.

From the document: "The United States has made significant progress toward achieving the President's affirmative vision for a digitally-enabled future, but emerging trends are creating both new opportunities for further advancement and new challenges to overcome. Malicious actors threaten our progress toward a digital ecosystem that is inclusive, equitable, promotes prosperity, and aligns with our democratic values. […] Deep and enduring collaboration between stakeholders across our digital ecosystem will be the foundation upon which we make it more inherently defensible, resilient, and aligned with U.S. values. This strategy seeks to build and enhance collaboration around five pillars: (1) Defend Critical Infrastructure, (2) Disrupt and Dismantle Threat Actors, (3) Shape Market Forces to Drive Security and Resilience, (4) Invest in a Resilient Future, and (5) Forge International Partnerships to Pursue Shared Goals. Each effort requires unprecedented levels of collaboration across its respective stakeholder communities, including the public sector, private industry, civil society, and international allies and partners. The pillars organizing this strategy articulate a vision of shared purpose and priorities for these communities, highlight challenges they face in achieving this vision, and identify strategic objectives around which to organize their efforts. To realize the vision these pillars lay out, we will make 'two fundamental shifts' in how the United States allocates roles, responsibilities, and resources in cyberspace. In realizing these shifts, we aspire not just to improve our defenses, but to change those underlying dynamics that currently contravene our interests."

From the document: "Racially and ethnically motivated violent extremism is becoming an increasingly common occurrence in the United States. Racially and ethnically motivated violent extremist (REMVE)-related terrorism has consequences beyond loss of life: It undermines the sense of safety that targeted groups feel in their country and unravels the social fabrics of trust that are necessary for society to function. Further still, REMVE attacks can motivate other like-minded attackers to follow up with their own attacks, as was apparently the case with the May 14, 2022, mass shooting in Buffalo, New York, by a self-avowed, internet-radicalized white supremacist whose manifesto drew heavily from the March 15, 2019, Christchurch mosque mass shootings, which also inspired a mass shooting in El Paso, Texas. Two key challenges for those who observe online spaces in which radicalization occurs are the sheer volume of data and the idiosyncrasies of online communities. Website-specific language and memes are difficult to track and parse; even if emerging terms are detected, defining them can be difficult."

All terrorist groups need finance to operate. It is a means for certain groups to accomplish their objectives; for others, it is the aims itself per se. Terrorist groups are therefore involved in different levels of organized crime. One of them is illicit drug trafficking, which has a nexus with organized crime and terrorist groups. This study aims to demonstrate a better understanding of the Kurdistan Workers' Party's (PKK) evolution into an organized criminal organization and its funding sources. From this point of view, the PKK is classified as a narco-terrorist organization with strong financial motives in this paper. As it will be analyzed on paper, its financial motivations frequently have weighed in the same level as its political motivation. It began to act as a hybrid organization through transnational offences, and it has steadily strengthened its criminal capabilities. Its members retain their deceptive political rhetoric to perform their illegal operations more easily. The organization can also be defined as a hybrid transnational organized crime group by UN standards, given the severity of its crimes and its criminal network spanning the Middle East, Turkey, and Europe

Local Planning for Terror and Disaster gives voice to experts in key fields involved with local preparedness, assessing the quality of preparedness in each field, and offering directions for improvement. Introductory chapters provide overviews of terror medicine, security and communications, which are indispensable to successful preparedness, while subsequent chapters concentrate on a particular field and how responders from that field communicate and interact with others during and after an event. Thus, a chapter by a physician discusses not only the doctor's role but how that role is, or should be, coordinated with emergency medical technicians and police. Similarly, chapters by law enforcement figures also review police responsibilities and interactions with nurses, EMTs, volunteers and other relevant responders.

Developed from topics at recent Symposia on Terror Medicine and Security, Local Planning also encompasses aspects of emergency and disaster medicine, as well as techniques for diagnosis, rescue, coordination and security that are distinctive to a terrorist attack. Each chapter also includes a case study that demonstrates preparedness, or lack thereof, for a real or hypothetical event, including lessons learned, next steps, and areas for improvement in this global era which increasingly calls for preparedness at a local level.

Given that the war on terror is currently being fought the way crime typically is―after the fact―this country cannot protect its citizens from future terrorist events solely in this way. Instead, measures must be taken to actually stop terrorists before they can attack. Here, the authors argue that government anti-terrorism policy must pay much more attention to reducing opportunities for terrorist attacks by protecting vulnerable targets, controlling the tools and weapons used by terrorists, and removing the conditions of everyday life that make these attacks possible. While some of this work is being done on an ad hoc basis, there are no recognized methods to guide the work, there is limited experience on which to draw, and the government has no trained professionals to oversee the work. In this book, the authors address these deficiencies, and lay out a systematic approach for reducing opportunities for terrorism.

The current take-them-out mindset may be the main reason why reducing opportunities for terrorism has been so neglected by governments, but another important reason is that the task seems so overwhelmingly difficult. How can we possibly protect every vulnerable target or person? How can we control all the everyday tools that terrorists must use in carrying out their attacks? How can we control their weapons when we cannot even keep guns out the hands of ordinary criminals? In this book, the authors show that these tasks are indeed manageable.

Military history texts discuss the historical record of armed conflict in the history of humanity, its impact on people, societies, and their cultures. Some fundamental subjects of military history study are the causes of war, its social and cultural foundations, military doctrines, logistics, leadership, technology, strategy, and tactics used, and how these have developed over time. Thematic divisions of military history may include: Ancient warfare, Medieval warfare, Gunpowder warfare, Industrial warfare, and Modern warfare.

Military strategy texts present ideas for military organizations to achieve their desired strategic goals. Military strategy discusses the planning and conduct of campaigns, the movement and disposition of forces, and how to deceive the enemy. Carl von Clausewitz (1780–1831), defined military strategy as "the employment of battles to gain the end of war." B. H. Liddell Hart defined strategy as "the art of distributing and applying military means to fulfill the ends of policy", which places more emphasis on political aims relative to military goals. Sun Tzu (544-496 BC) is the father of Eastern military strategy and greatly influenced Chinese, Japanese, Korean and Vietnamese war tactics. His book The Art of War has been very popular and has seen practical implementation in Western societies.

We analyze a sample of 47 major US cities to illuminate the mechanisms that lead Right-to-Carry concealed handgun laws to increase crime. The altered behavior of permit holders, career criminals, and the police combine to generate 29 and 32 percent increases in firearm violent crime and firearm robbery respectively. The increasing firearm violence is facilitated by a massive 35 percent increase in gun theft (p=0.06), with further crime stimulus flowing from diminished police effectiveness, as reflected in a 13 percent decline in violent crime clearance rates (p=0.03). Any crime-inhibiting benefits from increased gun carrying are swamped by the crime-stimulating impacts.

Australia’s 1996 National Firearms Agreement (NFA) banned several types of firearms and resulted in the government buying hundreds of thousands of the banned weapons from their owners. Studies examining the effect of removing so many weapons from the community have found that homicides, suicides, and mass shootings were less common after the NFA was implemented, although such incidents were declining prior to 1996. The strongest evidence is consistent with the claim that the NFA caused reductions in firearm suicides, mass shootings, and female homicide victimization. However, there is also evidence that raises questions about whether, for at least firearm suicides, those changes can be attributed to the NFA or to other factors that influenced rates of these outcomes around the time the NFA was implemented.

Good public policies are based on facts and data, and the most effective laws are written when policymakers understand the effects of such laws on a range of outcomes and can weigh the inherent trade-offs. As part of the RAND Gun Policy in America initiative, we conducted rigorous and transparent reviews of what current scientific knowledge could tell the public and policymakers about the true effects of many gun policies that are frequently discussed in state legislatures. Our first review, released in 2018, synthesized the available scientific data from studies published between 2004 and 2016 examining how 13 classes of state-level gun policies affect firearm-related deaths, violent crime, the gun industry, participation in hunting and sport shooting, and other outcomes. In 2020, we released an expanded and updated review, which added five new classes of gun policies and extended the period over which we conducted our literature search to span from 1995 to 2018. In 2023, we incorporated those studies in our updated analyses, drawing new or revised conclusions about the quality of evidence available to support claims about the effects of various policies.

From the Introduction: "The National Firearms Commerce and Trafficking Assessment (NFCTA) is a comprehensive examination of commerce in firearms in the United States and the diversion of firearms to illegal markets. Produced by a team comprised of ATF [Bureau of Alcohol, Tobacco, Firearms and Explosives] subject-matter experts, academics from a variety of disciplines specializing in research relating to firearms, and other law enforcement professionals, the NFCTA is designed to provide the public, researchers, and policymakers with analysis of data lawfully collected by ATF as part of its regulatory and law enforcement missions to inform the dialogue on firearm law and policy. To ensure comprehensive analysis, the NFCTA is being produced in several volumes. In May 2022, ATF published Volume I, 'Firearms in Commerce'. [...] ATF routinely generates bulletins for law enforcement and industry, and issues public safety advisories for all citizens. This Volume of the NFCTA, however, represents the first comprehensive report incorporating crime gun information from the full range of sources used by ATF in more than twenty years. Advancements in ballistic analytical technology and information processing during this period have enhanced ATF's capacity to support law enforcement efforts to identify, investigate, and prosecute those who use firearms to commit violent offenses and the traffickers who illegally divert those crime guns to criminals. Volume II describes in detail the sources of information that constitute CGI [Crime Gun Intelligence], and how CGI is leveraged to promote effective investigation of firearm-related violence. Finally, the information and analysis in NFCTA Volumes I and II set the foundation for the subject that will be addressed in Volume III, 'Firearms Trafficking.'"

BY National Integrated Ballistic Information Network (NIBIN

In 1997, ATF initiated the National Integrated Ballistic Information Network (NIBIN) program. Through this program, ATF provided for the first time comprehensive national automated ballistic imaging services to local, state, territorial, tribal, and federal law enforcement agencies across the country. NIBIN technology captures images of ballistic evidence, including cartridge casings1 recovered in shooting investigations (also referred to as “casings”) and test-fired cartridge casings2 from recovered crime guns (also referred to as “test-fires”), and stores those images in the NIBIN national database that conducts automated analysis for further review by expert technicians. Since 1997, law enforcement agencies have been submitting recovered ballistic evidence to ATF for entry into the NIBIN system, building a national and robust network of ballistic data. As of December 2021, approximately 5.2 million pieces of ballistic evidence have been entered into the system.

ATF and IAD cooperate with international law enforcement partners to disrupt transnational firearms trafficking and reduce violent gun crime in other countries. A central component of this effort is the use of ATF’s eTrace system to provide information on crime guns recovered and submitted for tracing by LEAs in foreign countries. Between 2017 and 2021, ATF received trace requests from an average of 75 countries involving approximately 33,000 crime gun trace requests on an annual basis. ATF continuously works to improve the tracing of crime guns recovered in other countries by completing formal tracing agreements with new international law enforcement partners and training them on the appropriate use of the eTrace system. As of 2021, ATF had eTrace Memorandum of Understandings (MOUs) with LEAs in 47 countries, representing 1,843 eTrace user accounts. To improve accessibility, Spanish language eTrace is available and currently used by law enforcement agencies in Mexico and other Central and South American countries.
