Prevalence of police in schools varies

July 12, 2018

This article reviews data on police assigned to schools. Two-thirds of high school students attend a school that has an officer assigned, compared to 45% for middle school and 19% for elementary school. School officers are most common in Virginia, South Carolina, Tennessee, and North Carolina, least common in New York, Pennsylvania, New Mexico, Iowa, and Michigan. The evidence on the impact of officers in schools on arrests, offenses, and student behavior is mixed and inconclusive.


Research in the ranks

June 25, 2018

This article reports the recent conference of the American Society of Evidence-Based Policing, which mainly featured current police officers presenting results from their own research. The organization, just a few years old, mirrors similar ones in the UK, Canada, Australia/New Zealand plus initial efforts in India and Mexico. The emphasis is on learning and applying what works, rather than simply relying on “what we’ve always done” or copying the latest popular idea from a neighboring agency.

Where killings go unsolved

June 7, 2018

This article analyzes over 50,000 homicides in U.S. cities, mapping neighborhoods with higher and lower clearance rates. There are variations between cities but also within, with fewer murders solved in low-income minority neighborhoods. Factors seem to include the challenge presented by drug- and gang-related cases, reluctant witnesses, lack of trust in police, and the resources devoted to homicide investigation.

Immigration enforcement — free-for-all in PA

April 13, 2018

This article details immigration enforcement by local and state police in Pennsylvania. Lacking any state-wide guidance or formal ICE partnership, individual agencies and officers make their own decisions about enforcing federal immigration laws, resulting in inconsistency and apparent ethnic profiling, particularly in central PA. One district attorney has warned chiefs that, since “officers are not permitted to independently enforce federal immigration law, they cannot extend the period of an investigatory stop to investigate immigration status without risking a constitutional violation.”

Tens of thousands celebrated in the streets, resulting in some property damage but no serious injuries and only 4 arrests.

Cyber crimes under-reported and under-investigated

February 5, 2018

This article discusses the huge challenge facing law enforcement agencies dealing with cyber crimes and other newer forms of hi-tech crime. One impediment is crime reporting systems designed a century ago. Efforts have been underway for 30 years to update and refine the Uniform Crime Reports, without much progress yet.

Black and blue

December 27, 2017

Relaxed residency requirement in Philadelphia

October 7, 2017

Philadelphia eased its longstanding residency requirement starting in 2010, allowing police with 5+ years tenure to live outside the city. Since then, about 15% of those eligible have moved to the suburbs, mainly for better schools, according to this article.

Pros and cons of data-driven predictions

September 9, 2017

This article provides a balanced look at the use of data and algorithms to make predictions in criminal justice, including policing. It shows how decision making accuracy can be improved but also explains that it ultimately comes down to questions of values and fairness that can’t be settled by science.
