( CNN ) The video appears to give us a rare glimpse into a police officer 's reaction after the fatal shooting of an unarmed man . Officer Grant Morrison approaches a patrol car and collapses . Fellow officers help him up , and he keels over the hood of the car , face in hand , sobbing . `` I thought he was going to pull a gun on me , '' Morrison , an officer in Billings , Montana , tells one of the officers assisting him . Since Missouri teen Michael Brown 's death prompted a move to put body cameras on all of America 's policeman , Americans will likely witness more recordings of the crucial moment when an officer decides to pull the trigger . It 's ugly , as a dash cam from Morrison 's patrol car reminds us . The video was presented as part of a coroner 's inquest into the April shooting of Richard Ramirez . A squad car 's headlights shine on Morrison as he walks away from a dark driveway in the background , where he had pulled over a car carrying Ramirez , who Morrison thought was a suspect in an armed robbery and shooting . Morrison shot the man after he did not comply with orders to keep his hands in sight , dash cam video shows . When Morrison reaches his fellow officer 's squad car -- with its dash cam also running -- he keels forward to the ground . He 's not wounded , but he sounds as though he 's hyperventilating . Morrison had just learned Ramirez , whom he shot three times , was unarmed . Morrison appears to sob when he stands back up , his voice squelching when he tells a colleague he thought his life was in danger . A colleague holds tight to Morrison as he appears to cry in heaves doubled over on the hood of the car . Another officer asks Morrison if she should call his wife . It was the second time the drug enforcement officer had shot and killed someone . Both times , dash cams were rolling . Both times Morrison faced an inquiry and the shootings were ruled justifiable , partly based on testimony analyzing the video , according to local media reports . In Ramirez 's case , Morrison said he was facing a suspected armed robber and shooter who he thought might pull a gun on him , CNN affiliate KULR reported . `` I wish I just knew he did n't have a gun but I could n't take the risk , '' Morrison told a court earlier this month . `` I could n't take the risk of him having a gun . I wanted to go home to my family and I wanted to see my son grow up . '' Despite the emotional breakdown -- and despite the inquest clearing Morrison of wrongdoing -- responses to a message posted by the Billings police chief on Facebook indicate there are plenty who feel Morrison used excessive force . `` He started out dropping f-bombs at the guy and then drew his pistol . He barely gave the guy a chance to surrender before plugging him three times at point blank range . This policeman is a murderer plain and simple , '' Tony Galasso wrote . `` Even a blind man can see ( and hear ) that this was wrongdoing on the coward cop 's part . He was all jacked up as soon as he got to the car . Swearing and yelling . He clearly knew who the guy he shot was and wanted to shoot him by the sound of his voice , '' Art Sharrard wrote . One person even invoked the so-called loud-music murder trial in Florida , in which Michael Dunn was convicted of murder , despite his claim that he saw a gun and acted in self-defense . `` It 's odd that Michael Dunn was convicted for murder in the first degree of Jordan Davis , even as his claim to self-defense against an imaginary weapon was nearly identical to Morrison 's , '' Troy Crumbo wrote . Morrison and the Billings police had their supporters , too . `` Folks , when a cop stops you , it 's not about you . It 's about law and order . Help out . Do what you 're told , '' Mona Letourneau responded , while Bryce Saunders posted , `` Well said , Chief ! ! Thanks for all you and your Department do for the Citizens of Billings keeping everyone safe . '' The other shooting involving Morrison happened in February 2013 in front of a suspected drug house . A man reached for a gun in his pocket . It turned out to be a BB gun , the Billings Gazette reported after the inquiry . That incident was also caught on video , and on it , you can hear Morrison and another man escalating into a shouting match . `` Get on the ground now ! '' Morrison yells . `` I 'm going to ( expletive ) shoot you ! '' The male voice continues shouting at the officer , who keeps commanding him to get onto the ground . There 's a pulsating electric sound -- perhaps a Taser -- then a bang that sounds like a gunshot . `` You shot him ? '' a woman 's voice later asks . `` He had a gun in pocket , '' Morrison answers . `` He had a BB gun , '' she yells . `` I did n't know that , '' Morrison responds . The man later died of his wounds . Opinion : Police body cams : Will they really help ?
