From the Washington Post:
More people were murdered last year than in 2014, and no one’s sure why

The number of homicides in the country’s 50 largest cities rose nearly 17 percent last year, the greatest increase in lethal violence in a quarter century.
A Wonkblog analysis of preliminary crime data found that about 770 more people were killed in major cities last year than the year before, the worst annual change since 1990.
The killings increased as some law enforcement officials and conservative commentators were warning that violent crime was on the rise amid a climate of hostility toward police. They said protests and intense scrutiny of officers who used lethal force had caused officers to become disengaged from their jobs, making streets more dangerous. Some have called it the “Ferguson effect,” after the St. Louis suburb in which Michael Brown Jr. was shot and killed by a police officer in 2014.
I blogged about this study last January.
The post-Ferguson spike in homicides was first documented by Carl Bialik in Nate Silver’s FiveThirtyEight last September 11, 2015. I blogged about it here.
