Factual error: When she lures the dog into the trunk of the Camaro, there are 2 factual errors. First, she flips down the rear seat to get into the trunk. Second generation Camaros did not have flip down rear seats. Then she pulls a handle under the dash to release the trunk lid. Camaros did not have this feature, either.
Continuity mistake: Towards the end of the film when the dog has jumped onto the car to attack Rocky, the red bag filled with money vanishes from the outside of the car, only to reappear shortly afterwards.
Continuity mistake: When the dog is trying to get to Rocky in the car, she first gets in the driver's door. Watch the window on the door. Its dirty before the dog even jumps up on it. When she gets in, the window is instantly clean. It becomes dirty again.
Continuity mistake: When the blind man drops the turkey baster, it's a lot fuller than when he started.
Plot hole: Of course the blind man can't see the intruders, but doesn't make any sense that the blind man wouldn't be able to smell them.
Chosen answer: As we see in the film, the houses they burgle have all purchased security systems from Alex's father. This makes it easy for them to gain access to the houses without triggering the alarm. However, if they committed a string of burglaries in which no alarms were triggered, people would eventually put together that customers of the same home security company were being burglarized and would point to them all being inside jobs. By tripping the alarm once they finish, they make it look like a standard break-in.
