How many police homicides in the US? A reconsideration

(This post is co-authored by Patrick Ball and Kristian Lum.) In early March, the Bureau of Justice Statistics published a report that estimated that in the period 2003-2009 and 2011, there were approximately 7427 homicides committed by police in the US. We responded that the method the analysts used, capture-recapture with two databases, is vulnerable to underestimation if the databases exhibit positive dependence. We conduct a thorough sensitivity analysis on the original independence model as applied to the police homicides databases. We used information from several other countries where our partners created multiple databases of homicides. We ...

HRDAG Analysis Supports Efforts to Hold Salvadoran Commanders Accountable for 1989 Jesuit Massacre

Almost a quarter century ago, on November 16, 1989, six Jesuit scholars, their housekeeper and her 15-year-old daughter were massacred inside the University of Central America (UCA) in San Salvador, El Salvador. Their chief target was the rector of the country’s leading university. The murders were carried out by members of the elite Atlacatl Battalion, acting on the direct orders of the highest-ranking members of the Salvadoran military. The United Nations–sponsored Truth Commission for El Salvador found that members of the Salvadoran military's high command “gave...the order to kill Father Ignacio Ellacuría and to leave no witnesses.” ...

Kosovo

During the conflict between NATO and Yugoslavia in early 1999, hundreds of thousands of people fled Kosovo, and thousands more were killed. Who were the perpetrators? Statistical analysis helped answer this question. While at the American Association for the Advancement of Science (AAAS), members of the HRDAG team wrote several reports on the conflict. With partners at ABA CEELI (American Bar Association/Central European and Eurasian Law Initiative), HRDAG submitted an expert report that was used in the trial of former Yugoslav president Slobodan Milošević at the  ICTY (International Criminal Tribunal for the Former Yugoslavia) in The  Hague, ...
