New York Governor Andrew Cuomo has announced plans to appoint a special prosecutor to investigate police killings of unarmed civilians. Cuomo said Tuesday he will appoint New York Attorney General Eric Schneiderman under a one-year executive order. The move will make New York the first state to institute an independent prosecutor for police killings, a step recommended by President Obama’s task force on policing. Cuomo’s move came the same day mothers of New Yorkers killed by police rallied outside his New York City office to accuse him of backtracking on a promise to appoint the special prosecutor if state lawmakers did not take action. Gwen Carr, mother of Eric Garner, who died after a police chokehold in Staten Island, said all cases should be investigated, not just those where police acknowledge the victim was unarmed. She also urged Governor Cuomo to appoint the special prosecutor for more than a year.

Gwen Carr: “We want justice for all, not for just some and just with the one year. One year is not enough. But he promised us that he would broaden the scope. It wouldn’t only be for one year; he would renew it after one year. And it wouldn’t be just for unarmed killings, because we know how things go. It’s not only — sometimes they’ll say the person was armed, and the person was not armed. We’ve seen South Carolina. We’ve seen different cases. But thank God for the videotape.”

That’s Gwen Carr, mother of Eric Garner, who died almost exactly one year ago, on July 17, after police pulled him to the ground in a chokehold and piled on top of him while he said, “I can’t breathe,” 11 times. A grand jury declined to indict Officer Daniel Pantaleo, who put Garner in the chokehold. The prosecutor in the case, Daniel Donovan, was recently elected to Congress. Garner’s death was caught on video by Ramsey Orta, who has been arrested repeatedly since Garner’s death. He alleges police harassment.
