Voter protection led to steep drop in racially biased arrests in late 20th century, study finds
Using voting records and arrest data from before and after the passage of the Voting Rights Act of 1965, a Brown economist found that increased enfranchisement led to fewer arrests for Black Americans.

PROVIDENCE, R.I. [Brown University] — In the midst of a national reckoning on racism and law enforcement, a Brown University economist has unearthed and analyzed decades-old data demonstrating that the fight to decrease racial disparities in policing might just start at the polls.
A new study co-authored by Brian Knight, a professor of economics at Brown, shows that the Voting Rights Act of 1965 not only enabled more Black Americans to vote, but also dramatically decreased the rate of Black Americans arrested in many places — a demonstration that fighting for enfranchisement for historically marginalized groups could play a major role in improving racial equality in the United States.
“We’re certainly not saying that equal voter representation eradicated the maltreatment of Black Americans by police,” Knight said. “What we do demonstrate in this paper is that in areas where law-enforcement officials are elected, if everyone has equal access to the vote, it can improve police officers’ treatment of Black Americans.”
The study was published on Monday, July 6, as a National Bureau of Economic Research working paper. Knight’s co-authors were Giovanni Facchini and Cecilia Testa of the University of Nottingham.
The passage of the Voting Rights Act (VRA) in 1965 marked a major turning point in Black Americans’ enfranchisement, Knight explained. Before the act was passed, Black women and men had the right to vote by law but were disproportionately affected by restrictive voting rules in many states, particularly in the South. Some citizens were barred from voting if they couldn’t pass literacy tests. Others couldn’t register to vote without presenting certain documentation, such as proof of long-term residency, and often had to navigate unorthodox business hours at registration offices.
After the VRA was passed, Knight said, the federal government sent examiners to districts with historically low voter turnout to monitor voting and registration procedures. The VRA also required those districts to obtain permission from the U.S. Department of Justice before changing their voting laws. As a result, the registration and voting process became more straightforward for all residents, and turnout among Black southerners surged between 1960 and 1968.
“It was very hard for Black Americans to vote in many states prior to the passage of the Voting Rights Act because of things like literacy tests that suppressed Black turnout,” Knight said. “The federal government’s oversight following the passage of the VRA played a critical role in ensuring Black Americans were not being turned away from voting and registering to vote.”
With more representation for Black voters, Knight said, came changes in local political leadership. In many Southern counties where police arrested peaceful Civil Rights protesters en masse, sometimes using violent tactics, Black voters ousted sitting sheriffs and police chiefs and instead threw their weight behind law enforcement leaders who expressed more support for the Civil Rights Movement and racial equality. The most famous example, Knight said, was in Dallas County, Alabama, site of the Selma march led by Martin Luther King Jr. Voters there famously voted out Sheriff Jim Clark, whose violent arrests of the protesters made national headlines.
Arrest data analyzed by Knight and his colleagues show that in counties where sheriffs were elected officials, where Black Americans made up a significant portion of the total population, and where Department of Justice oversight ensured equal access to the polls, arrest rates for Black Americans fell following the passage of the VRA. For example, in federally-monitored counties where the Black vote increased by 10 percentage points after the passage of the VRA, from 20% to 30%, post-VRA arrest rates of Black residents were 17% to 23% lower than in counties that were not federally monitored after the VRA passed.
The results, Knight said, provide evidence that the act increased accountability of law enforcement leaders and led to major changes in police behavior.
“We highlight some anecdotes in the paper that demonstrate that prior to the VRA, police treated Black Americans particularly poorly,” Knight said. “Our data demonstrate that giving Black people a real chance to vote didn’t eliminate all racial bias in arrests, but it improved the situation considerably.”
Knight said the results of the study demonstrate the inextricable link between equal voting rights and racial equality — an important connection to keep in mind in context of Shelby County v. Holder, a 2013 Supreme Court decision that stripped away key voter protections enshrined in the VRA. Today, states face considerably less federal accountability, and as a result, Knight said Americans of color have been disproportionately affected by new restrictions on voting, including voter identification laws and limited windows of time in which citizens can register.
The study also highlights the connection between public accountability and fairer practices in law enforcement. While most American sheriffs, who usually patrol highways and unincorporated county land, are elected by voters, a few are instead appointed by county leaders, giving local citizens no input in their selection. That’s also true of many municipal police chiefs, who are in charge of patrolling within their city limits; about half of U.S. police chiefs are chosen by voters, while the other half are appointed by mayors or other town officials.
Knight hopes his research drives Americans to investigate voter laws and selection processes of law enforcement leaders in their own districts, demanding change where it is needed.
“What we’re trying to emphasize in the paper is, for change to occur, we need political leaders to be responsive to the demands of voters,” Knight said. “Greg Champagne, the former president of the National Sheriffs’ Association, made the best possible argument for sheriffs as elected officials, rather than appointed officials: ‘…As opposed to a sheriff being appointed by a mayor or city council and being beholden to that city council, we are beholden to the people. We see our bosses as the citizens that elect us.’”
An analysis of 133 million tweets found that city-dwellers stay racially segregated as they eat, drink, shop, socialize and travel each day, demonstrating even deeper segregation than previously understood.
Researchers found that expanding access to long-acting reversible contraception methods, such as IUDs and implants, could give adolescents more agency in choosing whether and when to become pregnant again.
