WARNING: This video contains graphic content. Officer Grant Morrison's dashboard camera captured this video of his fatal shooting of Richard Ramirez during a traffic stop on April 14, 2014 in Billings, Montana.Story:After listening to more than 8 hours of evidence over two days, a coroner's inquest jury took just 30 minutes to determine Billings Officer Grant Morrison was justified when he shot and killed an unarmed man in April.Chief Rich St. John, who testified at the hearing, agreed."Our officers, as well as any other officer in the country, are authorized to use deadly force when there is an imminent threat of serious bodily injury or death," St. John told the jury during histestimony.Morrison testified that the actions of Richard Ramirez, who was killed during the encounter, left him no choice but to use deadly force."It was his left hand that was most concerning because he repeatedly refused to follow my commands to keep his hands up," Morrison said. "He continued to reach down to the area along his waste that I couldn't see whatsoever. I couldn't see what he was reaching for. I couldn't seewhere his hand was, it completely disappeared from my view and it was making me more and more afraid."Ramirez was killed when Morrison fired three shots.Montana Police Law Enforcement Academy Instructor Mike McCarthy argued that fear, paired with continued non-compliance, puts officers in a dangerous position."I believe whole-heartedly that any officer, knowing and feeling what officer Morrison knew, would do the same thing," he testified.Morrison told the jury he regrets having to shoot Ramirez."The hardest decision I've ever had to make," he said. "I wish I didn't have to make it. I wish I just knew he didn't have a gun, but I couldn't take the risk. I couldn't take the risk of him having a gun.And I wanted to go home to my family and I wanted to see my son grow up.Ramirez did not have a gun, but tests showed his blood contained a deadly level of methamphetamine.The drugs could explain Ramirez's failure to comply.But it was the video of the shooting, which the jury viewed again during their deliberations, that had arguably the biggest impact."My hat's off to law enforcement in Yellowstone County because they have embraced the technology available to them," said Yellowstone County Attorney Scott Twito after the verdict was announced. "And the video is really uncontroverted. The video shows in this case all the interactionthat led to the death of Mr Ramirez."Although the jury decided the shooting was justified, BPD has yet to release findings from its internal shooting review board.Those findings are expected to be released in the near future.
