On Sunday, thousands of protesters across the United States took to the streets to demand an end to police brutality in the wake of the death of Tyre Nichols.

The demonstrations come after a graphic video surfaced of a Memphis police unit beating Nichols to death. In response, the city of Memphis has since disbanded the unit and launched an investigation into the incident.

In Hollywood and downtown Los Angeles, protesters gathered to demand justice for Tyre Nichols and an end to police brutality. They held signs with slogans such as “Black Lives Matter” and “Justice for Tyre” and chanted “No justice, no peace” as they marched to City Hall.

The incident has sparked a national debate over the use of excessive force by police and calls for reform of the criminal justice system. In an opinion piece for The New York Times, contributor Mary K. Mitchell wrote that the death of Tyre Nichols “is a reminder of the urgent need to reform policing in America.”

In a piece for the Commercial Appeal, contributor Michael Robinson wrote that the city of Memphis must now “unify as one community” in order to prevent future tragedies like this one.

The protests are expected to continue throughout the week, and the nation awaits the outcome of the investigation into the death of Tyre Nichols.
