Yanez was charged with second-degree manslaughter and faced up to 10 years in prison.
"Mr. Castile's death was a awful tragedy ..."
A giant spray-painted canvas of Castile wearing a crown that read "Long Live the King" served as a backdrop for the rally. "My first-born son died". Central time, the State Patrol tweeted that they were arresting protesters "who failed to leave the roadway".
"When I was in court and they read the verdict I didn't feel too good, because I saw the Castile family and their hurt", he said. Saint Paul Police escorted the crowd they estimated to be 2,000 people.
She said civilization is "devolving, going back down to 1969".
Supporters of Philando Castile hold a portrait of Castile as they march along University Avenue in St. Paul, Minn., leaving a vigil at the state Capitol on Friday, June 16, 2017. Marchers also blocked commuter trains at one point and chanted "Yanez Guilty".
Castile's girlfriend, Diamond Reynolds, said she is "incredibly disappointed with the jury's verdict".
There was also video of the shooting captured from a camera mounted on the dashboard in Yanez's squad vehicle. He was trying to get out his ID and his wallet out of his pocket and he let the officer know he had a firearm and he was reaching for his wallet.
Ms Reynolds, whose video showed 32-year-old Mr Castile covered in blood as an officer pointed his gun at him, said he had been reaching for his licence when he was shot. The video showed blood oozing through Castile's shirt as he appeared to lose consciousness. "I'm just wondering when our voice will be heard".
Last summer, another demonstration on I-94 in response to Castile's shooting led to over 100 arrests or citations after protesters threw rocks, bricks, bottles and fireworks at police.
Prosecutors argued that Yanez did not see the gun and acted unreasonably.
Ramsey County Attorney John Choi, who made the decision to charge Yanez, said his office considered carefully before bringing the case.
"He was compliant", Choi said.
But no video existed of exactly what happened inside the auto in the key seconds before Reynolds began filming, leaving a jury to decide whether to believe Officer Jeronimo Yanez's testimony that Castile was pulling out his gun despite his commands and he fired in fear for his life. Leary, who is white, was assigned to the case after Yanez's attorneys asked to have another judge, who is black, removed.
"Justice was done", Gray told Reuters by telephone.
He added: "We're very happy. He was just doing his job". "The city intends to offer Officer Yanez a voluntary separation agreement to help him transition to another career other than being a St. Anthony officer", the statement said.
Minneapolis mayoral candidate Nekima Levy-Pounds said at the State Capitol rally, "We have a right to be sick and exhausted of being sick and exhausted ..."
