Does decision in chokehold case undermine call for police body cams?

(CNN) – A grand jury decided Wednesday not to indict New York Police Officer Daniel Pantaleo in the chokehold death of Eric Garner.

Video of the deadly July incident shows Garner raising both hands in the air and telling officers not to touch him. Seconds later, an officer behind Garner grabs him in a chokehold and pulls him to the sidewalk, rolling him onto his stomach.

"I can't breathe! I can't breathe!" Garner said repeatedly, his cries muffled into the pavement.

"Can you imagine if we didn't have this video what their story would be?" said attorney Benjamin Crump, a lawyer for Michael Brown's family. Crump is also working with the Garner family.

Crump said people have reached out to him, saying police body cams "'don't make a difference, because they just don't care about us.'"

"I disagree with that, I reject that," he said. "It's good when it's transparent. It's the system – when we see this here, it makes us say we've got to fix this system."
