On Thursday, President Biden released a statement appealing for calm as authorities prepare to release the footage this evening.
"I join Tyre's family in calling for peaceful protest," he said. "Outrage is understandable, but violence is never acceptable."
Memphis city police chief Cerelyn Davis, the first black woman in that role in Memphis, also called for calm amid what she said was a "failing of basic humanity toward another individual".

The five former Memphis police officers accused of second degree murder in the death of Tyre Nichols each face the same set of charges.
Tadarrius Bean, Demetrius Haley, Desmond Mills Jr, Emmitt Martin III and Justin Smith were booked into jail on Thursday.
They all joined the Memphis Police Department in the last six years, and were fired last week.
Here's a quick look at what the charges are, and what they mean:
Second degree murder - defined in Tennessee law as a "knowing killing of another", which need not premeditated
Aggravated assault - meaning an assault committed knowingly, which causes serious injury
Aggravated kidnapping - false imprisonment of a person. It is "aggravated" if the victim suffers an injury or happens if the assailant has a deadly weapon. Each officer faces two counts of this
Official misconduct - covers a range of wrongful acts by those acting as public servants. Again, each officer faces two counts
Official oppression - an offence which happens when a public servant intentionally subjects a victim to mistreatment, such as arrest or detention
Lawyers representing two of them say they will fight the charges.
Let's bring you some more background on the victim in all of this - Tyre Nichols.
His mother said her 29-year-old son had a passion for photography and sunsets. He would often go to nearby Shelby Farms Park on the eastern outskirts of Memphis.
Before his death, Tyre worked at delivery firm FedEx with his stepfather Rodney Wells.
After the press conference, a short video was played of Tyre skateboarding.
"You've got to put that skateboard down, you've got a full-time job now," his stepfather remembered saying.
"He looked at me like 'Yeah right', because that was his passion." Wells recalled.
