Calls-for-service represent the most basic form of public cooperation with the police. How cooperation varies as a function of instances of police activity remains an open question. The great situational diversity of police activity in the field, matching the situational diversity of crime and disorder, makes it challenging to estimate causal effects. Here we use homicides as an indicator for the occurrence of a standardized set of highly visible, socially-intensive, acute police investigative activities and examine whether police calls-for-service change in response. We adopt a place-based difference-in-differences approach that controls for local fixed affects and common temporal trends. Estimates of the model using data from Los Angeles in 2019 shows that calls-for-service increase significantly in the week following a homicide. The effect pertains to both violent crime and quality of life calls for service. Partitioning the data by race-ethnicity shows that calls-for-service increase most when the homicide victim is Black. Partitioning the data by race-ethnicity and type of homicide shows that some types of calls are suppressed when the homicide is gang-related. The results point to opportunities for police to build trust in the immediate aftermath of homicides, when the public is reaching out for greater assistance.

In a five-to-four decision announced in February of 2020, the United States Supreme Court ruled that the parents of an unarmed fifteen-year-old Mexican national killed by a U.S. Border Patrol agent in a cross-border shooting, cannot sue for damages in U.S. civil court. Here, we critique the majority and dissenting opinions and attempt to reconcile the strikingly different approach each used to resolve the case. Using a publicly available data set, we examine the homicide in Hernández v. Mesa, against the circumstances and context in which underage youth were killed by police within the United States over a five year period before, during and after the death of Michael Brown. The circumstances of the 121 cases suggest a greater need for police accountability if the justice system is to remain true to the protective “child saving” ideology that launched the founding of the juvenile court.

Suicide by cop (SbC) is a variant of victim-precipitated homicide. In SbC, a citizen intent on dying provokes police, often with credible threats of violence. A fatality results in ambiguity about manner of death (homicide versus suicide). Decedents’ families may raise claims of civil-rights violations, asserting insufficient restraint by officers. Police officers, when questioned, may justify their actions as reasonable and necessary force. Defendant officers and municipalities are concerned about police safety and adverse economic and public-perception consequences of litigation. This article explores the history and evolution of the SbC phenomenon, examines related civil case law, and reviews the contours of police-citizen interactions in SbC cases. There is potential liability for officers whose actions must be objectively reasonable to prevail in court. Since SbC can be admitted as evidence, there may be an expanded role for forensic psychiatry in distinguishing manner of death. Expert testimony can also aid fact finders in appreciating the decisions of officers faced with ambiguous and threatening situations. The author recommends collaboration between law enforcement and mental health professionals to improve recognition and handling of difficult situations involving persons with mental illness.

Why do certain incidents of serious violence end lethally whereas others do not? What role do personal characteristics of offenders and victims play and how do immediate situational factors influence outcomes? So far, these questions have not been subjected to much empirical scrutiny in criminological studies. This study, conducted in the Netherlands, seeks to answer these questions by explicitly comparing violent events that ended lethally with those that ended non-lethally. By taking into account offenders’ and victims' personal characteristics as well as immediate situational factors, it offers a more complete understanding of differences in outcome. It shows that immediate situational factors contribute more significantly to the outcome of violent incidents than generally thought. The study also presents an overview of murder and manslaughter in the Netherlands and puts these figures into international perspective. A separate chapter compares different types of violent events. The findings provide crucial criminological insights which may also guide efforts to reduce and prevent violent events from ending lethally in the future.
