Oakland Unite aims to interrupt and prevent violence by administering grants through a diverse set of strategies, which includes shooting and homicide response. Each year, this strategy provides $1.4 million in grants to community-based organizations that in turn offer services to hundreds of individuals. Grantees support two groups affected by gun violence: (1) those who have been the victim of gun violence or serious assault, and (2), those who have lost a loved one to gun violence. Grantees aim to address the immediate needs of shooting victims and their families; provide longer-term supports as the victims recover from injury or loss; and prevent retaliatory violence. Oakland Unite convenes and coordinates the network of providers and serves as the liaison between the network and law enforcement. The Oakland Unite 2019–2020 strategy evaluation report provides an in-depth analysis of the implementation of the four shooting and homicide response programs (summarized below), and the outcomes of participants over the 2016–2019 period. The evaluation’s findings suggest that shooting and homicide response offers needed supports to victims of violence and contributes to reducing re-injury and retaliation following a violent incident. As a single shooting injury can cost the city more than $1 million, the investment in these services has the potential to save the city considerable spending in the long run.

The police have the unique capacity to preempt and deter violence and to reduce the use of firearms in violent encounters. But overly aggressive policing tactics have contributed to a fraught relationship with low-income minority communities in which gun violence is heavily concentrated. Increased resources should be devoted to policing gun violence, but efforts of this sort must be targeted and disciplined. Effective policing requires a focus on the places and people that are at greatest risk; and there is a strong case for police agencies to increase the resources devoted to investigations of all criminal shootings, not just homicides. Successful policing of gun violence requires a productive working relationship with victims and their neighbors, which can be facilitated through observing community policing principles and respect for residents’ interests.

In 2020, consistent with historical trends, violent Criminal Code offences accounted for about one in every five crimes that came to the attention of police. Firearm-related violent crime typically represents less than 3% of police-reported violent crime in Canada; nevertheless, it has a significant emotional and physical impact on victims, families and communities. Additionally, rates of firearm-related violence have seen a general increase over the past several years. Concern about gun crime is long standing and a variety of approaches have been used to address it, including changes in legislation (see Text box 1). In April 2020, 22 people were killed in a mass shooting in Nova Scotia, the deadliest mass shooting in Canada in recent years. In particular, the Nova Scotia shooting led to a ban on assault-style firearms and renewed discussions around gun control and access to illegal weapons. This Juristat article uses data from the Uniform Crime Reporting (UCR) Survey and the Homicide Survey to provide a detailed examination of recent trends in firearm-related crime in Canada and the characteristics of these crimes over time and by region. In this article, firearm-related violent crime refers to victims of violent crimes where the most serious weapon present in the incident was a firearm and where police deemed the presence of the firearm relevant to the incident. Of note, for an incident to be considered firearm-related, a firearm need only be present during the commission of the offence, not necessarily used. This measure does not include non-violent Criminal Code offences where a firearm was present, including administrative offences such as unsafe storage, or firearm-specific violent offences such as discharging a firearm with intent where there was no victim identified. The article is divided into several sections beginning with an “Overview of firearm-related violent crime in 2020” examining geographic differences.1 This is followed by a section examining factors driving the change in firearm-related crime over 12 years, comparing two time periods (2009 to 2014 and 2015 to 2020) “Trends in firearm-related violent crime”. The article then examines the “Characteristics of firearm-related violent crime”, especially the types of violations involved and types of firearms present. This is followed by sections on “Characteristics of victims of firearm-related crime” as well as “Characteristics of individuals accused in violent incidents where a firearm was present”. Additional information is provided on non-violent weapons offences and firearm-related violent crimes involving organized crime or street gangs. The article uses data from the UCR trend file which contains information from 2009 to 2020. The article compares pooled information for the two six-year periods (2009 to 2014 and 2015 to 2020) to examine factors related to the increased rates of firearm-related violent crime observed in recent years.2 Combining the data into two six-year periods allows for a detailed examination of changes related to this overall increase. The periods were defined with reference to 2015 (before and after 2015) as 2015 was the year with the most notable increase in firearm-related crime over the 12 year period and this increase occurred in most jurisdictions. Moreover, 2015 was a notable year for crime in general as it marked the first increase in all police-reported crime since 2003. This article provides an analysis of police-reported firearm-related violent crime using currently available data. However, there are still many data gaps related to firearms used in crime. Statistics Canada has been working with police services to help improve information available on these types of crime.

From the document: "This report summarizes the connection between alcohol and firearm use, reviews existing state laws, and makes a core set of recommendations for addressing the problem at the state level: 1) 'Limiting access to firearms by persons with a record of alcohol misuse'[;] 2) 'Limiting access to guns when and where alcohol is consumed[.]' If these policy recommendations are to be effective, it is also important to address the environment where alcohol is sold and consumed. We therefore consider additional policies known to be effective in reducing excessive alcohol consumption and its related harms. In the last section, the report reviews key legal considerations that can help policymakers successfully implement the policies recommended in the report. The comprehensive approach of this report highlights the often-unexplored link between alcohol and gun violence. It is intended to become an essential resource for researchers, practitioners, policymakers, law enforcement professionals, and others working to reduce gun violence."

Gun violence is a major problem in the United States, and extensive prior work has shown that higher temperatures increase violent behavior. In this paper, we consider whether restricting the concealed carry of firearms mitigates or exacerbates the effect of temperature on violence. We use two identification strategies that exploit daily variation in temperature and variation in gun control policies between and within states. Our findings suggest that more prohibitive concealed carry laws attenuate the temperature–homicide relationship. Additional results suggest that restrictions primarily decrease the lethality of temperature–driven violent crimes, rather than their overall occurrence, but may be less effective at reducing access to guns in more urban areas.

Analysis from 750 cities of data available for the first times reveals that:

• The rate of people who died by gun suicide in cities increased 11 percent over the past decade, and now make up an average of over four in 10 city gun deaths.

• Cities in states with the strongest gun violence prevention laws have about half the rate of people who die by gun suicide as those in states with the weakest laws, demonstrating the importance of legislative action in preventing gun violence in cities.

• Cities with the most gun shops experience nearly four times higher rates of people who die by gun suicide than those with the fewest gun shops, signaling the importance of expanding cities’ focus beyond illegal guns.

• Smaller cities and those with fewer walkable neighborhoods (i.e., distance to local resources) experience higher rates of people who die by gun suicide, underscoring the importance of adequate access to resources and networks of social support that reduce risk factors like social isolation.

• Cities with the most parks have about half the rate of people who die by gun suicide as those with the least, suggesting that cleaning and greening efforts may offer benefits in reducing both gun homicides and suicides.

  Alcohol use and gun violence are leading causes of preventable injury and death in the United States. Alcohol kills 140,000 people annually;2 guns kill more than 48,000.3 Both of them are public health crises demanding strong policies. These issues are most deadly when they intersect with one another. An estimated 1 in 3 gun homicide perpetrators drank heavily before murdering their victims, 30% of gun homicide victims drank heavily before being killed, and a quarter of gun suicide victims were heavily drinking before they died by suicide.4,5 Despite alcohol clearly being a strong risk factor for gun violence, few attempts have been made to address this intersection. Heavy drinking was involved in: Nearly one third of all gun homicides A quarter of all gun suicides In 2013, the Consortium issued its first policy recommendation related to risky alcohol use and firearm access.i Five years later, the Consortium convened leading experts to reassess this recommendation about firearm prohibitions associated with DUIs as an effective policy measure to prevent firearm-related deaths while ensuring racial equity in enforcement. During the COVID-19 pandemic, excessive drinking increased by 21% and alcohol-related deaths increased approximately 25%.6 At the same time, gun sales increased by 40%, gun homicides by 35%, and gun suicides had the largest one-year increase ever recorded.7,8 These alarming trends urge us to think about alcohol misuse as a risk factor for gun violence. To better understand this connection, the Consortium, in partnership with the Center for Gun Violence Solutions, developed this report to highlight the available research to inform policy. As detailed in this report, alcohol misuse is associated with a risk of dangerous firearm behaviors, interpersonal firearm violence, and gun suicide. Although data about how this dangerous intersection affects different communities is limited, people of color are disproportionately affected by both gun violence and alcohol misuse. This report summarizes the connection between alcohol and firearm use, reviews existing state laws, and makes a core set of recommendations for addressing the problem at the state level: 11 Limiting access to firearms by persons with a record of alcohol misuse 2) 2 Limiting access to guns when and where alcohol is consumed

Firearm homicides and suicides represent an ongoing public health concern in the United States. During 2018–2019, a total of 28,372 firearm homicides (including 3,612 [13%] among youths and young adults aged 10–19 years [youths]) and 48,372 firearm suicides (including 2,463 [5%] among youths) occurred among U.S. residents (1). This report is the fourth in a series* that provides statistics on firearm homicides and suicides in major metropolitan areas. As with earlier reports, this report provides a special focus on youth violence, including suicide, recognizing the magnitude of the problem and the importance of early prevention efforts. Firearm homicide and suicide rates were calculated for the 50 most populous U.S. metropolitan statistical areas (MSAs)† for the periods 2015–2016 and 2018–2019, separated by a transition year (2017), using mortality data from the National Vital Statistics System (NVSS) and population data from the U.S. Census Bureau. Following a period of decreased firearm homicide rates among persons of all ages after 2006–2007 in large metropolitan areas collectively and nationally, by 2015–2016 rates had returned to levels comparable to those observed a decade earlier and remained nearly unchanged as of 2018–2019. Firearm suicide rates among persons aged ≥10 years have continued to increase in large MSAs collectively as well as nationally. Although the youth firearm suicide rate remained much lower than the overall rate, the youth rate nationally also continued to increase, most notably outside of large MSAs. The findings in this report underscore a continued and urgent need for a comprehensive approach to prevention. This includes efforts to prevent firearm homicide and suicide in the first place and support individual persons and communities at increased risk, as well as lessening harms after firearm homicide and suicide have occurred.

Firearm homicides and suicides represent a continuing public health concern in the United States. During 2015-2016, a total of 27,394 firearm homicides (including 3,224 [12%] among persons aged 10-19 years) and 44,955 firearm suicides (including 2,118 [5%] among persons aged 10-19 years) occurred among U.S. residents (1). This report updates an earlier report (2) that provided statistics on firearm homicides and suicides in major metropolitan areas during 2006-2007 and 2009-2010, and places continued emphasis on youths, in recognition of the importance of early prevention efforts.

Introduction: The majority of homicides (79%) and suicides (53%) in the United States involved a firearm in 2020. High firearm homicide and suicide rates and corresponding inequities by race and ethnicity and poverty level represent important public health concerns. This study examined changes in firearm homicide and firearm suicide rates coinciding with the emergence of the COVID-19 pandemic in 2020. Conclusions and Implications for Public Health Practice: During the COVID-19 pandemic, the firearm homicide rate in the United States reached its highest level since 1994, with substantial increases among several population subgroups. These increases have widened disparities in rates by race and ethnicity and poverty level. Several increases in firearm suicide rates were also observed. Implementation of comprehensive strategies employing proven approaches that address underlying economic, physical, and social conditions contributing to the risks for violence and suicide is urgently needed to reduce these rates and disparities

In recent years, policy attention to firearm violence in the European Union (EU) has increased greatly. A thorough insight into the problem is an important step in developing such a policy. How many firearms are circulating in the EU? How many deaths are caused by firearms? Is there a relationship between gun ownership and the number of violent deaths (homicides and suicides)? And what is the impact of firearms legislation? The European Commission has already said that ‘a lack of solid EU-wide statistics and intelligence hampers effective policy and operational responses’. The research of the Flemish Peace Institute offers a starting point to fill this need.

This is the interim report of the Investigative Committee on the Robb Elementary Shooting of the Texas House of Representatives. Conscious of the desire of the Uvalde community and the public at large to receive an accurate account of the tragedy at Robb Elementary School, the Committee has worked diligently and with care to issue this interim report of its factual findings. The Committee’s work is not complete. We do not have access to all material witnesses. Medical examiners have not yet issued any reports about their findings, and multiple other investigations remain ongoing. The Committee believes this interim report constitutes the most complete telling to date of the events of and leading to the May 24, 2022, tragedy. This Committee has prioritized factual accuracy, as will be evident from our attention to conducting our own interviews and documenting our sources of information. Still, based on the experiences of past mass-shooting events, we understand some aspects of these interim findings may be disputed or disproven in the future. The Committee issues this interim report now, believing the victims, their families, and the entire Uvalde community have already waited too long for answers and transparency.

In New Zealand, 250,000 licensed shooters own an estimated 1.1 million firearms, enough for one in each occupied dwelling and sufficient to outnumber the combined small-arms of the police and armed forces by a ratio of 30 to 1. We own 16 times as many guns per capita as the English and the Welsh, 60% more than the Australians but less than half as many as the residents of the United States. An additional 14,000 guns are imported to New Zealand in a typical year. Each day an average of seven firearm offences involving danger to life are reported to the police, while one in five homicides are committed with a firearm. On average, one person dies by gunshot in New Zealand every four days. Despite a common certainty that firearms are increasingly misused, there has been little local research. Although critical data on the misuse of firearms are collected by police, these are not made available.

"In 2017 there were 30 separate active shootings in the United States, the largest number ever recorded by the FBI during a one-year period. With so many attacks occurring, it can become easy to believe that nothing can stop an active shooter determined to commit violence. [...] Faced with so many tragedies, society routinely wrestles with a fundamental question: can anything be done to prevent attacks on our loved ones, our children, our schools, our churches, concerts, and communities? There is cause for hope because there is something that can be done. In the weeks and months before an attack, many active shooters engage in behaviors that may signal impending violence. While some of these behaviors are intentionally concealed, others are observable and -- if recognized and reported -- may lead to a disruption prior to an attack. Unfortunately, well-meaning bystanders (often friends and family members of the active shooter) may struggle to appropriately categorize the observed behavior as malevolent. [...] Once reported to law enforcement, those in authority may also struggle to decide how best to assess and intervene, particularly if no crime has yet been committed. By articulating the concrete, observable pre-attack behaviors of many active shooters, the FBI hopes to make these warning signs more visible and easily identifiable. This information is intended to be used not only by law enforcement officials, mental health care practitioners, and threat assessment professionals, but also by parents, friends, teachers, employers and anyone who suspects that a person is moving towards violence."

The Commission conducted 15 meetings open to members of the public. The Commission received statements from an extensive list of State and local officials and private persons who had experience with or information concerning the event; Commission staff reviewed thousands of pages of official and unofficial documents, reports, and studies. Two recommendations related to crisis response actions. First, law enforcement policy and training should emphasize that the highest priority of law enforcement officers, after arriving at the scene of a crisis, is to stop any ongoing assault. Second, there should be an increased emphasis on training appropriate personnel in preparation for and responding to large-scale emergencies. Two recommendations pertained to improved communications for critical emergencies. First, law enforcement agencies should plan their communications systems to facilitate crisis communication with other agencies with whom they might reasonably be expected to interface in emergencies. Second, Colorado should continue to develop a single statewide digital trunked communications system. Other categories of recommendations pertained to advance planning for critical emergencies; interaction with media representatives; tasks of school resource officers; detection by school administrators of potential perpetrators of school-based violence and administrative countermeasures; medical treatment for attack victims; reuniting attack victims and their families; identification of victims' bodies and family access to bodies; and suicide prevention in the aftermath of traumatic incidents.

In January, 2013, the Office of the Child Advocate was directed by the Connecticut Child Fatality Review Panel to prepare a report that would focus on Adam Lanza (hereinafter referred to as AL), and include a review of the circumstances that pre-dated his commission of mass murder at Sandy Hook Elementary School. The charge was to develop any recommendations for public health system improvement that emanated from the review. Authors of this report focused on AL’s developmental, educational, and mental health profile over time, the services he received from various community providers, and ultimately his condition prior to his actions on December 14, 2012. Authors looked for any warning signs, red flags, or other lessons that could be learned from a review of AL’s life. It was not the primary purpose of this investigation to explicitly examine the role of guns in the Sandy Hook shootings. However, the conclusion cannot be avoided that access to guns is relevant to an examination of ways to improve the public health. Access to assault weapons with high capacity magazines did play a major role in this and other mass shootings in recent history. Our emphasis on AL’s developmental trajectory and issues of mental illness should not be understood to mean that these issues were considered more important than access to these weapons or that we do not consider such access to be a critical public health issue.

In the wake of several high-profile shootings at schools in the United States, most notably the shootings that occurred at Columbine High School on April 20, 1999, the United States Secret Service (Secret Service) and the United States Department of Education (ED) embarked on a collaborative endeavor to study incidents of planned (or "targeted") violence in the nation's schools. Initiated in 1999, the study, termed the Safe School Initiative (SSI), examined several issues, most notably whether past school-based attacks were planned, and what could be done to prevent future attacks. The SSI findings highlight that in most targeted school-based attacks, individuals, referred to as "bystanders" in this report, had some type of advanced knowledge about planned school violence. Despite this advanced knowledge, the attacks still occurred. This study aimed to further the prevention of targeted school-based attacks by exploring how students with prior knowledge of attacks made decisions regarding what steps, if any, to take after learning the information. The study sought to identify what might be done to encourage more students to share information they learn about potential targeted school-based violence with one or more adults. Six key findings were identified. Given the small sample size and the exploratory nature of the study, generalization from these findings may be limited. The findings are: (1) The relationships between the bystanders and the attackers, as well as when and how the bystanders came upon information about the planned attacks, varied; (2) Bystanders shared information related to a threat along a continuum that ranged from bystanders who took no action to those who actively conveyed the information; (3) School climate affected whether bystanders came forward with information related to the threats; (4) Some bystanders disbelieved that the attacks would occur and thus did not report them; (5) Bystanders often misjudged the likelihood and immediacy of the planned attack; and (6) In some situations, parents and parental figures influenced whether the bystander reported the information related to the potential attack to school staff or other adults in positions of authority,
