Students and residents came together Sunday at the New Haven Green to rally in solidarity with Tyre Nichols' family.
Demonstrators mentioned Dr. Martin Luther King Jr.'s comment that an injustice anywhere is a threat to justice everywhere.
Nichols died three days later.
Cox was in handcuffs and had no seatbelt on.
Organizers said the scope of this incident is not on race, but rather on policing.
