10 July 2017 :

Police nationwide shot and killed 492 people in the first six months of this year, a number nearly identical to the count for the same period in each of the prior two years.
The Washington Post began tracking all fatal shootings by on-duty police in 2015 in the aftermath of the 2014 killing in Ferguson, Mo., of Michael Brown, who was unarmed and had an altercation with the officer who shot him.
The ongoing “Fatal Force” project has documented twice as many shootings by police in 2015 and 2016 as ever recorded in a single year by the FBI’s tracking of such shootings, a pattern that is emerging again in 2017. Since Brown’s killing in Ferguson, other fatal shootings by police, many captured on video, have fueled protests and calls for reform. Some police chiefs have taken steps in their departments to reduce the number of fatal encounters, yet the overall numbers remain unchanged. Academics who study shootings give weight to The Post’s accounting. As in previous years, the data gathered by The Post showed that police most frequently killed white males who were armed with guns or other kinds of weapons.
One in four people killed this year were mentally ill. And police have continued to shoot and kill a disproportionately large number of black males, who account for nearly a quarter of the deaths, yet are only 6 percent of the nation’s population. This year, fatal shootings of unarmed people have declined, continuing a trend over the past two years. In the first six months of this year, 27 unarmed people were fatally shot, compared with 34 for the same period in 2016 and 50 in the first six months of 2015.
Black males continued to represent a disproportionately large share of unarmed people killed, although their share has dropped slightly: from 32 percent of all unarmed killings during the first six months of last year to 26 percent for the same period this year. Mental illness has remained a factor in fatal police shootings, as a quarter of those killed were struggling with some form of mental illness. The pace at which officers have been killed in the line of duty has held steady over the past two years. According to the FBI, 21 police officers were killed from January to June 29, two fewer than in the same period last year. The 2016 year ended with 66 officers killed, not including accidental deaths. Since January 2015, according to the FBI, 128 police officers have been killed in the line of duty. In Los Angeles from January 2015 to the end of last month, city police officers shot and killed 47 people, the most for any U.S. police department in the period. Officials with the Los Angeles Police Department said they have been working to reduce the number of deadly encounters. In the past two years, the department extensively tracked use of force, added training and updated its use-of-force policy, which now requires officers to “de-escalate” confrontations before firing their guns.
This year in Los Angeles, fatal shootings are down to seven, which Matthew Johnson, president of the Los Angeles Police Commission, considers a small victory. There is no comprehensive government data source that tracks fatal shootings by police officers. The Post database relies on local news coverage, public records and social-media reports to identify fatal shootings by police.
The FBI gathers information on fatal police shootings, but that program is based on voluntary reporting by police agencies and covers only cases in which police fatally shoot people who are committing felonies. The Post’s data has revealed a dramatic undercount by the FBI.
The Post’s project, and a similar counting effort by the Guardian newspaper in 2015, prompted now-fired FBI director James B. Comey to call his own agency’s system “embarrassing and ridiculous.” In October 2016, the Justice Department announced that it would move forward with plans to collect better data about officer-involved shootings.
