Police stops and naïve denominators | Crime Science

A comparison of the racial composition of police stops to the entire population of a city or jurisdiction is frequently cited as evidence of racial bias in proactive policework. This article argues that using base population is naïve to the realities of the distribution of crime and policing. Using the example of Philadelphia, PA (USA), the impact of different benchmarks to estimate racial disparity in stop data is demonstrated. The range of alterative benchmarks include the spatial distribution of calls for service, the locations of violent crimes, and the demographic composition of suspects in crime as reported by the public. The article concludes by arguing that if cities ask police departments to prioritize certain problems and places, benchmarks to which police are held accountable should better reflect those priorities.

How Mask Bans Threaten Free Speech, From New York to North Carolina | The Marshall Project

The problem with relying on identification technologies or some type of biometric technology is that you have to have a database that can compare the captured real time data. There is no all-encompassing database where cell phone usage can identify a person or facial recognition can identify a person. It’s difficult to identify a person after the incident.

Removing the mask would act as a deterrence. Why do people rob banks with masks on, because they don’t want to be identified. People who go to protests and act illegally would be deterred from doing so if they couldn’t wear masks. Most people are uncomfortable greeting a mask wearing stranger at their house. That’s because there is a certain connotation about people’s motives when they are wearing masks.

Privacy advocates worry banning masks at protests will encourage harassment, while cops’ high-tech tools render the rules unnecessary.

Trends in Gun Theft – Council on Criminal Justice

Hundreds of thousands of crimes involving firearms occur each year in the United States. In 2022, for example, guns were used in more than three quarters of murders, one third of robberies, and a quarter of aggravated assaults.1 But less is known about how people who use guns in violence acquire their weapons.

One source of guns used in crimes is theft.2 While research on the role of gun theft in gun crime is limited,3 a small but growing body of evidence suggests that stolen guns may play a significant role in violent crime. Stolen guns are more likely than other guns to be recovered in crimes,4 and gun crime appears to increase in neighborhoods from which guns have been recently stolen.5 Despite the potential importance of stolen guns as a source of guns used in crime, data on gun theft trends are limited
