When Sgt. Button and Lieber pull down and arrest the spectator who is sitting on the platform underneath the lights, the spectator's hands are free when they pull him down into the seats. In the next shot, as the spectator lies on his stomach in between the seats, his arms are bound behind him by twist-tie handcuffs. In the next shot, his hands are free, and Lieber is putting the twist-tie handcuffs around the spectator's wrists.
Tyler's girlfriend wakes up with her arms above her head and starts talking to Charlie, but in the next camera shot her arms are on her side and chest.
When Pratt, the SWAT team member, is climbing up to the stadium lights platform, he is first shown in a long shot climbing up the fixed rung ladder attached to the platform's support pole. A close-up then shows Pratt climbing up the steel extension ladder that he used a moment before to ascend to the support pole. A wide shot then shows him ascending the fixed rung ladder on the support pole again.
Before the shooting starts there are many people in the corridors away from the seats and out of sight of the gunman, the police would most certainly have evacuated them from the building and any one else who had left the stadium for whatever reason and certainly not allowed them to return to their seats where they are in danger of being shot.
Captain Holly refers to the rifle the sniper is carrying, as an "automatic" and a "semi-automatic". The Remington Model 742, also known as the Woodsmaster, is not an automatic, but a semi-automatic rifle that was produced by Remington Arms from 1960 until 1980.
While moving into their firing positions at the stadium, several SWAT members have their fingers on the triggers of their M16 rifles. This violates a basic rule of gun safety, which says that the finger must stay off the trigger until the sights are on the target. Until that time, the finger should be placed alongside the trigger guard.
