after watching the video frame by frame, I think this was what happened. when the policemen heard the gun shots they were all alerted right. then iboko went to the door of their post to check out what was happening that was when he saw the theif sagging he tried shooting at him but missed due to tension and shot the floor. that was when the guy at the back of the car used bullet to break car glass in a bid to shoot the officers inside. the guy on blue started spraying the police post.
