While looking over the victim in the photo booth, the victim's head changes position several times without any apparent intervention by the CSI techs.
The dried up blood on the victim shot in the head at the beginning of the episode can be seen running down the victims body as if they were standing up for a period of time after being shot. Instead, the victims blood should have obviously ran down the side of their face towards the ground as they would have dropped immediately after being shot in the center of the forehead.
When Lamont Moore is found dead, he is clearly seen breathing. (Stomach rising up and down).
