"Keep on doing it, but do it in peace."
Those are the words of Eric Garner's mother, Gwen Carr, who on Saturday in Harlem encouraged and welcomed the thousands of people taking part in ongoing marches calling for justice.
"It is just so awesome to see how the crowds were out there," USA Today reports Carr as saying. "They are out there. They are standing for my son. My heart is overflowing with joy. It's just a gracious feeling."
Garners' widow, Esaw Garner, told the crowd: "Just keep fighting. Keep fighting for what's right, to get justice."
Reuters reports: "Sunday was expected to see protests again in New York as well as Chicago, Philadelphia, Miami and Minneapolis and dozens of other cities."
Dozes of marches and "die-ins" took place in dozens of cities on Saturday as well.
In Seattle hundreds of protesters marched to the Seattle Police Department to protest the killings of Garner and Michael Brown.
In Berkeley, California, protesters faced tear gas from police.
In Chicago protesters
blocked the Eisenhower Expressway and Lake Shore Drive.
In Atlanta, hundreds of protesters issued a call to "Choke the system."
In the world of professional sport as well, a growing number of athletes are using their platform to protest the killings.
An NBC News survey meanwhile has shown a stark racial divide on public confidence in police forces.
The poll found that 47 percent of Americans say that they believe police apply different standards to blacks and whites, while 82 percent of African-American respondents did.
And while the recent grand jury decisions not to indict the officers who killed Garner and Michael Brown caused 43 percent of Americans to lose faith in the justice system, the number was 70 percent among African-Americans.
