Now, though to the graphic new videotape of the case of a retired police captain who shot seeing the moment the shot was fired. Look closely at the right side of your screen there. You see the victim's arm reach over the chair and grab the shooter's popcorn and throw it at him then the gun comes out and is fired. On Friday the judge in this case made a major decision and Ryan smith has the story. I want to detain Mr. Reeves pretrial. Reporter: Obvious relief. The reaction overnight of any coal oulson after hearing a judge deny bond to the accused murderer charged with shooting and killing her husband, 43-year-old Chad oulson in a movie theater last month after an argument over texting? I'm happy and relieved by the judge's rulingment. I have no doubt in my mind it was the right decision and want it thank the state. Reporter: It comes after new surveillance video played in court shows the incident unfolding inside the theater. Here is reeves leaning over his seat telling oulson not seen on camera to turn his cell phone off then he gets up to talk to the manager of the theater. Minutes later, reeves is back. Then the moment that changed everything. Watch closely. Oulson seems to grab something, throw it in reeves' direction. That's when reeves draws his gun and shoots. Watch again. The confrontation and the gunshot over in seconds. As soon as I pulled the trigger, I said, oh, this is stupid. Heard in court audiotapes from police interviews just after the shooting. Scared the hell out of me. I thought the guy was fixing to beat the Out of me. I was defending myself. I guy was very aggressive. Reporter: Oulson said he was not aggressive. I did not see any pushing or shoving. Reporter: Even reeves who pled not guilty admits to police he regrets pulling the trigger. If I had to do it over again, it would have never happened. We would moved. Reporter: For Curtis reeves unless a court overturns his bail decision he'll stay behind bars until a jury of his peers decides his fate. For "Good morning America," Ryan smith, ABC news, Atlanta. Such incredible video, our thanks to Ryan.
