Chris Rock has made a lot of news lately, weighing in on racism and the epidemic of police violence toward minority communities in America. His recent appearance on Letterman did not disappoint either. "I saw Sting backstage," he joked, "I had to throw up my hands, I'm scared of the police."

"Dave, do you realize that even pro-wrestling has outlawed the chokehold? So the WWE has better standards than the NYPD," he laughed.

Rock is referring to the non-indictment of the police officer who killed Eric Garner, a Staten Island father of six, who died after being put in a chokehold when selling loose leaf cigarettes on a street corner. Garner's case was the second high profile incident of a black man killed by a white police officer where no charges were filed. In November there was no indictment for Ferguson, Mo. police officer Darren Wilson in the shooting death of 18-year-old Michael Brown who was unarmed when Wilson killed him.

In this clip below, Comedy Central's South Park also lampooned the dubious practices of police, with a group of white officers all shouting, "It's a black guy! Choke him! Shoot him! Shoot him and then choke him!"

Jokes aside, Americans are starting to organize for a more equitable criminal justice system. Earlier this week, thousands of protesters gathered in Berkeley, California to rally for better policing standards; and today, a number of civil rights organizations will march on Washington, D.C, under the banner #Justice4All.
