• Undocumented immigration does not worsen drug, alcohol problems in U.S.: Study

    Despite being saddled with many factors associated with drug and alcohol problems, undocumented immigrants are not increasing the prevalence of drug and alcohol crimes and deaths in the United States, according to a new study. According to the study, rather than increasing substance abuse problems, a 1 percent increase in the proportion of the population that is undocumented is associated with 22 fewer drug arrests, 42 fewer drunken driving arrests and 0.64 fewer drug overdoses — all per 100,000 people. The frequency of drunken driving fatalities was unaffected by unauthorized immigration rates.

  • George Mason’s new Center of Excellence for Criminal Investigations and Network Analysis

    DHS S&T has selected George Mason University in Fairfax, Virginia to lead a consortium of U.S. academic institutions and other partners for a new Center of Excellence (COE) in Criminal Investigations and Network Analysis (CINA). The Center’s research will focus on criminal network analysis, dynamic patterns of criminal activity, forensics, and criminal investigative processes.

  • Identifying, analyzing drone-collected evidentiary data

    DHS awards nearly $1 million to a Colorado company to develop ways to increase law enforcement capabilities to identify, collect, and analyze evidentiary data from consumer and professional drones. The award is part of S&T’s Cyber Forensics, a project which focuses on development of new capabilities to help law enforcement with the forensic investigations of digital evidence from various devices such as mobile phones and automobile infotainment systems.

  • Treating gun-shot victims: Initial hospital costs just “tip of the iceberg”

    Gun violence resulted in initial hospitalization costs of more than $6.6 billion nationwide from 2006 through 2014 — an average of $734.6 million per year, according to a new study.The $6.6 billion figure is just the tip of the iceberg: It does not include costs of emergency room visits or hospital readmissions.American tax payers bear about 40 percent of the total costs of treating victims of gun violence.

  • Community racial bias predicts use of lethal force by police

    Researchers developed a predictive model of lethal force by integrating crowd-sourced and fact-checked lethal force databases with regional demographics and measures of geolocated implicit and explicit racial biases collected from 2,156,053 residents across the United States. They found that the racial biases of Whites in a community predict how many African-Americans are killed by police in a given area.

  • A spate of acid attacks in London is part of an international problem

    A series of five acid attacks in one night in London has created a moment for the British government to take a more public stance on this growing problem. Available statistics suggest a sharp rise in attacks with corrosive substances in the United Kingdom. Data produced by the Metropolitan Police reveal that there were 455 crimes involving corrosive substances in London alone in 2016. Dozens of incidents have been reported so far this year. It is also clear that acid violence is a global problem. Acid Survivors Trust International reports a significant number of attacks in India, Colombia, Pakistan, Nepal, Bangladesh, Uganda, and Cambodia. There is thus a need to think about how to identify and support good practice internationally – in terms of prevention and supporting victims. This can help the efficient sharing of expertise and resources globally.

  • Optimal policing: When should the police use confrontational tactics?

    Citizens depend on police to provide public safety while maintaining the trust of the community. How can democratic societies balance these two, often conflicting, aims — given citizens’ often divergent views over basic tenets of criminal justice policy? Researchers outline a “formal model of optimal policing” that can be used to resolve tensions between public safety and community trust — and that also can help a public that is prone to privileging one over the other, depending on the circumstances, to keep both in mind.

  • Why police reforms rarely succeed: Lessons from Latin America

    Americans have mobilized extensively in the past three years against police brutality, militarization, and corruption through the Black Lives Matter and related movements. Government officials at the federal level have responded to these demands by creating specialized task forces to recommend best practices, and investigating troubled police departments and enforcing reforms. Courts have also worked to roll back unconstitutional stop-and-frisk policies, while city governments have created independent oversight agencies and enacted robust community policing programs. But will it stick? My research on police reform in Latin America shows that such reforms are highly vulnerable to political reversals. These cases reveal how they can be quickly rolled back before they can take hold and demonstrate results. Understanding the politics of police reform in Latin America may be informative for those who hope for changes in policing in the U.S.

  • German right-wing Reichsbürger movement a terror threat: German intelligence

    The German Federal Criminal Police (BKA) have reported that the followers of the right-wing Reichsbürger movement could engage in “extreme violence, including terror acts.” A comprehensive report, compiled by German law enforcement services, concluded that the movement is more dangerous to public safety than other right-wing and nationalist German political movements. The Reichsbürger movement – which is somewhat similar to the U.S. Sovereign Citizen movement – is not considered the most extreme right-wing politically, and its followers are not organized in the traditional sense.

  • Gun violence prevention groups adopt moderate, middle-ground positions to meet goals

    A new study found that American organizations identifying as gun violence prevention groups advocate for the right to bear arms and for some gun purchase and ownership conditions, which they argue will curb gun-related injuries and deaths. The finding contrasts with some depictions of gun violence prevention groups as “anti-gun.”

  • Violence in news toughens opinions on crime, punishment

    If it bleeds, it leads, as the saying goes: Violence is omnipresent in media, and when consumed through news on a regular basis, it drums up support for continuing the status quo in the criminal justice system. That’s one finding from new research which examined how media consumption and social networks influence anxiety about crime and opinions about the justice system.

  • Psychopathic brains’ wiring leads to dangerous and violent actions

    Researchers have found that psychopaths’ brains are wired in a way that leads them to over-value immediate rewards and neglect the future consequences of potentially dangerous or immoral actions. Psychopaths “are not aliens, they’re people who make bad decisions,” one researchers said. “The same kind of short-sighted, impulsive decision-making that we see in psychopathic individuals has also been noted in compulsive over-eaters and substance abusers.” Psychopaths are “exactly what you would expect from humans who have this particular kind of brain wiring dysfunction.”

  • Decrease in lead exposure in early childhood likely responsible for drop in crime rate

    Exposure to lead in the preschool years significantly increases the chance that children will be suspended or incarcerated during their school careers, according to new research. Conversely, a drop in exposure leads to less antisocial behavior and thus may well be a significant factor behind the drop in crime over the past few decades.

  • Immigration does not raise crime: Studies

    Immigration has no effect on crime, according to a comprehensive examination of fifty-one studies on the topic published between 1994 and 2014. The meta-analysis is the first on the relationship between immigration and crime. The reviewed studies most frequently found no relationship between immigration and crime. But among those that did find a correlation, it was 2.5 times more likely that immigration was linked to a reduction in crime than an increase.

  • Gun policy preferences across racial groups

    In the wake of recent mass shootings in Alexandria, Virginia, and elsewhere in the United States, a new study looks at factors that drive support for gun control among whites, Latinos, and blacks. The researchers found support for all forms of gun control is stronger among Latinos and blacks than whites. For example, 74 percent of blacks and 61 percent of Latinos, but only 55 percent of whites support an assault weapons ban.
