For centuries, juries in the US have consistently exonerated whites, especially police officers, charged with murdering Black Americans. Few cases were brought to trial. Those that did rarely won convictions.
In the 20th century, it seemed possible that new horrifying graphic evidence might flip this script. Photographs and videos of attackers and those they killed or mutilated began streaming into the national consciousness. But even in the Civil Rights era, when networks aired prime-time footage of police beating Black Americans with batons wrapped in barbed wire, and siccing dogs on children, little seemed to change.
