Corrected entry: The movie never explained what happened to Anderton's child. For all Anderton knows, the boy could be still alive. The boy's disappearance was the cause of the divorce, and the ending implies that they were reconciled as a result of resolving the kidnapping, but it was never resolved.
Corrected entry: Precrime is only an active force in Washington DC, and the Precogs therefore only dream up murders which will occur in the district. Why didn't Burgess just lure Anne Lively out of the district to kill her rather than constructing the elaborate plot which eventually led to his downfall?
Corrected entry: When the pre-cogs see a murder the name of the victim and perpetrator are written on either a red ball, for crime of passion, or on a brown ball, which means the murder was planned. John's name is written on a brown ball, but how could he have planned to kill this man if he never knew him?
Corrected entry: I've been thinking about this alot, and I've realized that the whole idea of comitting a murder to look like an "echo" after another one wouldn't work. If you think about it, that system would work to cover up the visual part of the premonition, but how would it stop a ball from being created? Burgess definitely planned to kill Anne Lively, so it should have been a brown ball. If you compare his plan to kill Lively to any other murder, than there's really no difference except that he hired someone else to murder her too. Early on in the film, after Anderton throws the ball across the table and Witwer catches it, he mentions that the precogs don't see what you intend to do, only what you do. So if the guys was hired to pretend to kill Lively, the brown ball would have still said Lamar Burgess, the real killer. If the fall guy thought that he was going to kill her, then there would have been two brown balls, one for Lamar and one for him, or one brown ball for the both of them. No matter how you slice it, there should have been a ball. Some people think that the techs would have dismissed it as an echo before it ever got to the ball stage, but there must be a system to identify echoes beyond a tech saying "yeah, that looks the same". The names are clearly innate to the vision, so both visions, however similar they looked would have different murderers attached to them.
Corrected entry: In the film a woman says that she was about to be raped, but was saved, thanks to pre-crime. But later they say that pre-crime can't detect rapes.
Corrected entry: The pre-cogs can only see murders because they are the most disruptive events, we are told. However, when Anderton and the pre-cog are walking through the mall, she sees trivial things well enough to tell him to take an umbrella, when a guy walking by will drop a briefcase, etc. How do these rate as disruptive enough to be seen?
Corrected entry: There is a basic paradox of the vision of the Crow murder. Anyone wonder what brought this vision on? The visions take place when the first "domino" falls in a series of dominos that lead to a murder, days ahead of time for a premeditaded murder or hours or minnutes before for a crime of passion (in the one we see, as soon as the husband gets suspicious the vision occurs). So what triggered this vision? What was the first domino? The paradox is that the vision itself was the first domino. Without the vision there was no reason for Aderton to track down a man named Leo Crow. So the vision somehow triggered itself. And without the vision, Aderton would not have attempted to track Leo Crow and the murder wouldn't have occured.
Corrected entry: It seems illogical that two computers in the same room would not be networked together in the future. Both computers by the Temple can read from the pre-cogs, but the pre-cops use a person to run across the room with a futuristic disc to transfer information between computers! That doesn't even happen today anymore...
Corrected entry: If Anderton's murder of Leo Crow was premeditated and thus a brown ball and he had been thinking about it for six years, wouldn't the ball have dropped earlier?
Corrected entry: At the squat where the eye surgery is performed, the lid is left off the ice chest. Yet 6 hours later there is enough unmelted ice to nearly fill the bathtub.
Corrected entry: When John shows his gun to the hotel clerk he does not pick it up when he goes to catch Agatha and then goes upstairs. How does he manage to shoot Leo without a gun?
