The anger behind the protests, explained in 4 charts

Police killings have trended upward in recent years — and black men are more likely to be killed.

The protests that have risen up in nearly every city in the United States over the past week were sparked by the killing of an unarmed black man, George Floyd, by now-fired police officers in Minneapolis. Even though one former officer, Derek Chauvin, has been charged with third-degree murder, protests have continued night after night because they are not just about that single killing but what it represents: rampant police brutality that seems to have no consequences.

In fact, a recent analysis by advocacy group Mapping Police Violence found that 99 percent of police killings from 2014 to 2019 did not result in officers even being charged with, let alone convicted of, a crime.

Mapping Police Violence’s data, which is gathered from public databases and law enforcement records, also shows that the number of police killings has trended slightly upward from 2013 to 2019 — in that span, the number of killings falls to a low of 1,050 in 2014, and has a high of 1,143 in 2018. For comparison, 373 people were killed in mass shootings in 2018 and about 1,010 Americans died of Covid-19 on May 30.

Numbers such as these are a stark reminder that despite years of demonstrations and advocacy — and even changes in policy, such as the adoption of body cameras or requirements that officers use deescalation techniques before resorting to violence — little has changed numerically.

Those numbers are of killings of people of all races — but the same can be said when looking at the data broken down by ethnicity: killings of black Americans by police appears to be trending slightly downward, as are the killings of white Americans; the killings of Latinx Americans are slightly up. Police killings of Native and Asian Americans have spiked, then fallen; the killings of Americans of unknown race are very much up.

Those are totals, and reminders that police killings are not just a problem suffered by black Americans — that they affect Americans of all ethnicities. But controlling for population (that is, looking at killings per million people) shows that it is black Americans who are most likely to be killed by police officers — that they are nearly twice as likely to be killed as a Latinx person and nearly three times more likely to be killed than a white person. Black Americans are also about 1.4 times more likely to be unarmed in fatal interactions with police than white Americans are (and about 1.2 times more likely to be killed unarmed than Latinx Americans).

This disparity is such that in eight US cities — including Reno, Nevada; Oklahoma City, Oklahoma; and Scottsdale, Arizona — the rate at which police killed black men was higher than the US murder rate. And in 27 of the country’s 50 largest cities, the rates of police killings (of people of all races) is higher than the rates of violent crime. In many cities, like Kansas City, Missouri, and Columbus, Ohio, counting police killings as violent crimes would more than double the rate of violent crime.

It is this reality that people are protesting. There have been many protests against police killing unarmed black men in recent years, some of which have gone on for weeks, like the 2017 St. Louis protests over the killing of Anthony Lamar Smith by former police officer Jason Stockley, and the 2014 uprisings in Ferguson that followed the killing of Michael Brown. Out of those protests have come the Black Lives Matter movement and other advocacy initiatives, as well as oversight, like the consent decree the Baltimore Police Department entered into with the Department of Justice following the 2015 killing of Freddie Gray.

And some studies have shown that the adoption of measures pushed for by these advocates has helped reduce police killings broadly — a Mapping Police Violence analysis of data from the Police Use of Force Project found that chokehold and stronghold bans reduced killings by 22 percent, for instance.

Those reductions, however, have not been enough. The protests have not been enough. Mapping Police Violence’s analysis shows this, as do other studies, like one from researchers at Rutgers University, the University of Michigan, and Washington University in St. Louis recently explained by my colleague Dylan Scott.

Using data from 2013 to 2018, the researchers worked to understand how at risk American men and women were of being killed by police. The results showed black men had a 1 in 1,000 chance in being killed by police — just higher than the odds the the average American has of dying in a motorcycle crash, according to the National Safety Council.

If past protests have not changed this tragic paradigm, it is not clear that the present ones will either. But there is little else protesters can do than to draw attention to this problem that has not gone away. While many have been encouraged to vote, Mapping Police Violence’s data shows that these killings take place in cities with a broad range of leadership types, and regardless of which party is in control.

Many advocates argue that no change can come about until policies are put in place weakening police unions, and ensuring police cannot be militarized or demilitarized at the whim of the president of the United States. The decision to offer police military equipment is not made at the local, but federal level. And police union officials, who often shape the rules police officers are governed by, are voted in by officers in the union — not by the public.

Also, as Scott notes, complaints about police action are not always looked into — Chauvin had 18 complaints against him, but was nevertheless allowed on the street the day of Floyd’s killing. And again, 99 percent of officers are not charged following killings. With little other recourse than to attempt to press for change — and with decades, even centuries, of frustration fueling them — the protests will continue.

As Olga Hall, a protester in Washington, DC, told the Associated Press Saturday night, “We’re sick of it. The cops are out of control. They’re wild.”
