However, lesbian women reported lower levels of legitimacy compared to other groups due to compound minority stress from sexism and homophobia. The study adds em...
A study analyzes how hip-hop artists like Jay-Z and Public Enemy use 'cop voice' in their songs to interrogate police violence in black communities. Researchers identify the phenomenon of 'cop voice' as a racialized way of speaking used by police to provoke fear and extreme compliance from people of color.
Researchers found that body-camera footage led to lower intentionality ratings compared to dashboard footage in both real and staged incidents. The study suggests that body-camera footage could impact judicial decisions.

Researchers developed an Ensemble Poisson Kalman Filter (EnPKF) algorithm that combines urban crime data and ETAS model for real-time forecasts on crime rates and predicted hotspots. The algorithm has been tested on over 1000 violent gang crimes in Los Angeles, showing promise as a tool to support law enforcement
Research by Maria Cristina Morales found that first- and second-generation Latinos are more likely to be questioned about their citizenship status than those who have been living in the US for longer. This phenomenon, known as citizenship profiling, highlights the disproportionate surveillance of Latino immigrants and their children.
A series of experiments by David Levari et al. shows that people perceive threatening stimuli as abundant even when they are decreasing in reality. This perception bias affects important decisions, such as those made by police officers or research ethics board members.
A new study from the University of Texas at Austin found that empathetic police officers who feel undervalued perform poorly in their duties. In contrast, conservative officers with punitive approaches to justice tend to maintain high performance levels despite public criticism. Policymakers are urged to address the issue by implementi...
A new study published in The Lancet found that police killings of unarmed black Americans are associated with worse mental health among other black Americans. Researchers surveyed nearly 40,000 black Americans and estimated that these deaths contribute to 1.7 additional poor mental health days per person every year.
A new study reveals that police killings of unarmed black Americans have a significant impact on the mental health of black American adults in the general population. The quasi-experimental study found an estimated 55 million excess poor mental health days per year among black American adults due to police killings.
Research suggests that police officers on night shifts are more likely to receive public complaints due to elevated fatigue. Going to court during the day after a night shift further increases this risk, highlighting the need for duty schedules to consider court appearances.
A QUT study found that cyclists are more seriously hurt in crashes with motor vehicles at intersections with 'Stop' or 'Give-way' signs than at intersections with traffic signals. The study, analyzing 13 years of Queensland police crash records, found drivers were most often at fault at these intersections.
A study found that tweets containing moral rhetoric may signal whether a protest will turn violent. Researchers developed a model to detect moralized language, which nearly doubled on days when clashes among protesters and police became violent.
Non-White homeless adolescents are more likely to report police harassment and be arrested, but elements of living on the street offset racial disparities. Visibility and past experiences play a role in subsequent events leading to arrest.
A recent study by Northwestern University researchers used network science to map the gun market in Chicago, finding that individuals are on average 2.5 handshakes away from a gun. Gang membership was found to reduce this distance by 27 percent, highlighting the role of gangs in facilitating access to guns.
Researchers found that virtual avatar-to-avatar interviews increased accurate information recall by up to 60% compared to traditional face-to-face interviews. This innovative approach reduces distractions and promotes honesty, making eyewitness testimony more reliable.
Research estimates that police violence resulted in over 57,000 years of life lost in 2015-16, disproportionately affecting young people and people of color. The study uses The Counted database to track deaths and injuries due to police violence, highlighting the need for better data to inform policy.
A former police chief and LEAP UK argue that harsher drug laws are ineffective in reducing violence and suggest a shift towards public health policies. They point to the failure of punitive approaches and highlight the need for regulation, taxation, support, and education.
According to Philip Cook's analysis, gun thefts represent only about one percent of all gun transactions in the US. In Chicago, only a tiny proportion of crime guns were ever reported stolen to the Police Department.
Purdue researchers have developed an online platform called the Social Media Analytics and Reporting Toolkit (SMART) that filters social media content according to key words and geographic regions. The tool is being used by first responders to analyze both live and historical data, helping them attend to certain areas faster.
The study, led by George Mohler, found no statistically significant difference in arrest rates by ethnic group between predictive policing and standard patrol practices. The researchers also discovered that arrests were higher in algorithmically-selected areas but remained unchanged when adjusted for crime rates.
A field-data study in Los Angeles found that predictive policing did not result in biased arrests, with arrest rates by ethnic group showing no statistically significant difference. However, the researchers noted that higher crime rates and proportionally higher arrest rates were observed in algorithmically selected areas.
A study of NYC's stop-and-frisk policy from 2006 to 2013 found a link between height and police stops for black men. The research also replicated findings in experiments, highlighting the role of perceived threat in racial stereotyping.
A multi-site study found that police use of force is rare, accounting for less than 1% of all calls and arrests. Most significant injuries were associated with firearms and dogs, while conducted electrical weapons like Tasers were rarely used in force incidents.

A new study by Boston University School of Public Health researchers found a strong association between structural racism and racial disparities in fatal police shootings at the state level. States with higher levels of residential segregation had higher rates of unarmed black victims killed by police, even controlling for arrest rates.
A recent study published in Preventive Medicine reveals that dating partners are more likely to engage in violent behavior and account for a larger percentage of domestic violence incidents compared to spouses. The research found that over 80% of intimate partner violence incidents involve current or former boyfriends and girlfriends.
A new study published in PLOS ONE found that social media coverage of fatal police-citizen incidents can act as a virtual contagion, leading to future violence against law enforcement. The research also suggests that an unexpected increase in officer line-of-duty deaths is associated with an increase in the number of minority citizens ...
A simulation model found that investing in targeted policing and the community-based strategy Cure Violence can effectively reduce urban violence. The study suggests that a combination of both approaches may be more effective than either alone.
A recent study by University of Kansas researchers found that people's racial and political identities strongly influence how they view the causes of deadly police encounters. African Americans, liberals, and Democrats generally attribute fatal encounters to broader problems in policing. The researchers recommend that police department...
A study found that police officers are highly responsive to rules and supervision, leading to more conservative tactics after the NYPD mandated detailed stop reports. The intervention increased the perceived level of supervision, resulting in a sharp drop in unnecessary stops and a rise in the hit rate.
