Justice for Tire Nichols are demanded by these protesters in Memphis, Tennessee.
It has been three weeks since the death of African American Tire Nichols, who was brutally beaten at a traffic stop.
The protests were triggered by a shocking video released by the authorities.
Street surveillance cameras and the so-called bodycams - cameras that officers have to wear on their bodies - recorded the brutality of the operation.
You can see how Nichols is first treated by the officers with a taser gun and tear gas on January 7th.
Then the police repeatedly punch and kick their victim.
Three days later, Nichols succumbs to his injuries and dies in a hospital.
In Memphis, around 50 people initially took to the streets after the video was published, and several hundred in other cities such as Washington and New York.
US President Joe Biden said people were right to be outraged, but also called for calm and peaceful protests.
The police officers responsible have been arrested.
They are charged with second-degree murder, aggravated assault and kidnapping, among other things.
Deadly police violence against black people is common in the United States.
In most cases - although not in the case of Tire Nichols - white police officers are the perpetrators, as in the case of George Floyd, who was killed in Minneapolis in May 2020 when he was arrested.
