The New York grand jury that decided not to indict Officer Daniel Pantaleo in the chokehold death of Eric Garner heard testimony from 50 witnesses and studied 60 exhibits over nine weeks of deliberations, reports Yahoo! News.

A brief order was released on Thursday from Stephen Rooney, a Staten Island judge who fulfilled the request of Staten Island District Attorney Daniel Donovan to publicly release details about the grand jury proceeding-mainly that the grand jury was shown four videos and heard the testimony of 50 witnesses, 22 of them civilians.

The grand jury found "no reasonable cause" to bring charges against the officer, according to District Attorney Daniel Donovan.

When the grand jury's decision to not charge Pantaleo was announced Wednesday, protests erupted in New York and across the nation. New Yorkers chanted, marched and blocked traffic in the streets. Police arrested 83 people, the majority on disorderly conduct charges, according to Yahoo! News.

Police union officials, along with Pataleo's attorney, claim the New York Police Department (NYPD) officer used an authorized takedown move against Garner, 43, who was resisting arrest. They said Garner's poor health-not a banned chokehold-was the cause of his death.

In order for Pantaleo to be found criminally negligent, the grand jury would have had to determine he knew there was a "substantial risk" his actions would cause Garner to die.

Officers attempted to arrest Garner on July 17 for selling untaxed cigarettes on the street. The incident was captured on video showing Pantaleo holding Garner in a chokehold as he repeatedly said, "I can't breathe."

Although the medical examiner ruled that the chokehold played a part in Garner's death, Rep. Peter King, (R-N.Y.), defended the grand jury decision, saying Garner's death was mostly due to his health issues that included diabetes, heart trouble and obesity.

"The fact that he was able to say it meant he could breathe," said King. "And if you've ever seen anyone locked up, anyone resisting arrest, they're always saying, 'You're breaking my arm, you're killing me, you're breaking my neck.' So if the cops had eased up or let him go at that stage, the whole struggle would have started in again."

National Urban League President Marc Morial and many other civil rights leaders believe the lack of charges brought against Pantaleo was "a travesty of justice."

Civil rights leaders gathered Thursday at the Rev. Al Sharpton's National Action Network headquarters to deliberate. Sharpton told the Associated Press that a Dec. 13 march in Washington is planned, followed by a civil rights summit to discuss boycotts and education.

Attorney General Eric Holder said federal prosecutors will investigate Garner's death. The NYPD is also conducting an internal investigation that could result in administrative charges against Pantaleo. Pantaleo remains on desk duty.
