As I noted:
You can time it so that you hit Pause right at 8:26:53 and you will see that is when he swings the gun barrel up. At that time, the cops can not be heard yet and he hasn't been shot yet.At 8:26;53, he swings the barrel up. By 8:26:55 it is pointed straight down. At 8:26:55:10 the barrel has swung so that it's pointing *behind him*
Then hit Play and watch the barrel swing back down and hit Pause when the gun barrel is pointed straight down. The time will be 8:26:55
Then hit Play again and watch the barrel continue swinging back until it is pointing behind him (and towards the floor)
Then the cop yells, the barrel swings to be pointing straight down and Crawford is shot and falls.
