6:44 Note that there are no visible wounds on the man laying in the doorway.
6:47 A woman's voice screams out in agony but no women have yet been shot. An audio soundtrack has been edited into this video. Thus, it's not a live video.
6:50 Note that there is a man with a gray shirt laying in the doorway to the right. In addition, note that the door is fully open and the man's right arm is approximately one foot from the door. He appears dead. Further note that people are fleeing this room out the back door.
6:52 to 6:53 As Tarrant walks down the hall, a magazine for his gun can be seen on the floor to the left. Tarant will pick up this magazine from this exact location at 8:32. This is the exact staging area where Tarrant later reloads. Thus, it appears this scene had multiple takes with a magazine being mistakenly left from a prior scene.
6:52 to 6:53 During this same time period, a man in blue runs across the doorway at the end of the hall and appears to be shot by Tarrant. PLEASE NOTE THE PSYCHOLOGICAL TRICKERY TAKING PLACE HERE! You just saw that this is a real person in blue. Later you'll see him get shot in the head. What you can't wrap your mind around, however, is that between these two scenes, the man is blue is switched out for a mass casualty dummy with a blood pack. Tarrant is shooting something here but most likely blanks or some kind of special effects gun so that nobody gets injured.
6:57 Tarrant reaches the end of the hall and is now firing into the large room. He fires straight ahead and left, but only up to a 45 degree angle. He shots won't be able to hit anyone farther left than 45 degrees because he didn't turn far enough left.
6:57 to 6:58 Tarrant turns to fire right. Although Tarrant has been firing his weapon for 23 seconds now, including several shots within this room, nobody on the right side of the room has reacted or taken cover. Tarrant quickly realizes that it looks fake that nobody on the right is reacting so he quickly turns back to the left side of the room.
6:59 As Tarrant turns for a split second back to the left side of the room, we notice a couple of things. First, a man in a gray shirt and jeans is laying on the ground with his head under some kind of furniture. This man didn't appear in the video as Tarrant entered this room shooting. Further, where this man is laying is not even close to the 45 degree angle that Tarrant turned into as he fired. We never see the man in the gray shirt move and it's impossible that he was shot as Tarrant entered the room. Thus, he is most likely a mass casualty dummy. Also note that there is a pile of what appear to be people in the corner that aren't moving. We have to ask why aren't they moving as they would not have been in the 45 degree angle range that Tarrant fired into. Thus, as the gray shirt man and the pile of people were supposed to have already been shot, we must realize what happened here. Tarrant made a minor mistake as he entered the room. As he turned left and fired into this room, Tarrant was supposed to turn his gun a full 90 degrees to the left while firing. Tarrant messed up here.
