Five Memphis police officers were charged with second-degree murder within 20 days of the death of 29-year-old Tyre Nichols.
Civil rights attorney Ben Crump said this example of "swift justice" should set a precedent for future cases of police aggression.
Tyre Nichols died three days after being held at a traffic stop and beaten by Memphis police officers.
"We have never seen swift justice like this," Crump said at a press conference in Memphis' Mount Olive CME Church.
Crump called out the "institutionalized police culture" that he attributes for the death of Tyre Nichols.
