Other mistake: Despite the city-wide outage from the storm, there's quite a visible glow around the house as Sarah and Nick investigate the grounds, that isn't moonlight.
Suggested correction: A personal generator? Or (more likely) a generator from the CSI gear?
Continuity mistake: In the scene where Nick and Sara discover the brother they are looking for is dead, the froth in his mouth changes between shots and in one shot he has no froth in his mouth.
Continuity mistake: In the scene where Jules whacks the slot machine, you see a small dent up close, but in the next shot the wheel is badly damaged. When you see Jules move to the table, the wheel is not damaged at all.
Continuity mistake: In the scene where Sara is talking to Avery while he is packing his bag, you see him wrapping the headphones around his iPod and putting them in the bag, but in the next shot he puts them in his bag again.
Continuity mistake: By the helicopter you can see that they are loading the victim on the chopper, and the police officer is inside already. 10 seconds later when CSI Brody is running towards the chopper, the 2 men carrying the victim are now 5-10 feet away from it. (00:02:20)
