The 24 seconds of video shows Siale Angilau, a member of the Tongan Crips gang, standing up at the defense table, grabbing a pen or pencil, then running to the witness stand and hurdling himself over it.
THIS shocking footage reveals the moment a Crips gang member is shot dead in court after launching at a witness with a pen. He was not hurt, the "Daily Mail" reports.
That's when an unidentified United States marshal shot Angilau four times.
"The video completely contradicts plaintiffs' argument that Angilau stopped posing a danger within less than one second of launching himself over the witness stand while making a stabbing motion with a pen in hand", Dowdell wrote in the verdict, Deseret News reported.
Angilau's family wanted a jury to see the video to see if the marshal used appropriate force after the Federal Bureau of Investigation found the shooting was justified.
Angilau's lawyer, Robert Sykes, urged the judge to release the video so that the jury could see and decide if excessive force was used in the shooting.
The 2014 courthouse video was released today after a years-long legal battle by a media coalition, who argued it was a public record in an important police use-of-force case.
Video of the moment Angilau attacked the witness.
He points out that Angilau was already down on the ground for the final three shots and that a courtroom full of officers could have stopped him to stop him before he harmed anyone with the pen.
A United States marshal fired four times at close range at the defendant inside as he rushed to the witness stand, jumped and swung with a pen at a shackled witness.
They were allowed to view the video but not release it.
Angilau's family filed a wrongful death lawsuit, claiming the shooting was "particularly unreasonable, reckless and constitutionally excessive".
'There was no necessity to use force'.
As he was on the floor, he was shot four times (in quick succession) by a nearby police marshal.
Angilau was one of 17 people named in the 2010 indictment against Tongan Crip members, accusing them of assault, conspiracy, robbery and weapons offences.
His family have not yet decided if they will appeal the judge's dismissal of their lawsuit. Angilau was the last person to be tried, as previous defendants were sentenced to 10 to 30 years behind bars.
Faces of nearly all the people present inside the courtroom at the time, including the judge is blurred in the video.
Department of Justice attorneys said the media organizations wanted the video to "sell newspapers".
