"Mr. Marks, by mandate of the District of Columbia Precrime Division, I'm placing you under arrest for the future murder of Sarah Marks and Donald Dubin that was to take place today, April 22 at 0800 hours and four minutes."
One of the implications of Seers
(and Time Travel
) is that we are able to predict crimes. If we can predict them, then we can prevent the crimes from happening. This trope is about taking evidence from the future, and preventing the criminal from doing what they have already will be done.
Without knowing the future, society prevents additional crimes from happening by punishing the people caught committing them. Precrime Arrest, however, is when a character who is known to be going to have committed
specific crimes is punished in order to prevent them from committing those crime (or crimes) in the first place. The offender, if caught early enough, may suffer from Bewildering Punishment
because they haven't even thought
of committing the crime yet.
Attempts to arrest/execute Hitler are popular enough to form their own trope: the Hitler's Time Travel Exemption Act
. Examples of Time Travel being used for Hitler specifically belong there.
Anime & Manga
Film - Live-Action
- Psycho-Pass takes place in future Japan of 2112, where Japan is governed by the Sibyl System, which measures many psychological factors. One of the things determined by scanning people is the "Psycho Pass": the probability and severity of the crimes a person might commit. Those who have a high enough "Psycho Pass" are arrested or killed by Dominators, a type of gun used by the police. People who have a high "Psycho Pass", but haven't committed any crimes, are called "latent criminals". They generally have two choices: Be arrested and rehabilitated, or work for the police.
- In the short story "All the Troubles of the World" by Isaac Asimov, the Multivac supercomputer is used to churn through data about the population and predict crimes before they occur, allowing authorities to make precautionary arrests and investigations. The plot kicks off when the subject of one such arrest has no idea what he's being arrested for, and Multivac subsequently reports that the predicted crime (a murder) has increased in probability since the arrest.
- In Through the Looking-Glass, the White Queen tells Alice that the King's Messenger (the Hatter, or 'Hatta', by the illustrations) is in prison for a crime he has not yet committed, or been tried for. (This is Looking-Glass Land, which is in some ways time-reversed.)
- Doctor Who: "Let's Kill Hitler" features the obvious Hitler's Time Travel Exemption Act, from Melody Pond and from new character/crew Justice Department Vehicle #6018. The Justice vehicle is sent to painfully kill Time's greatest criminals just before their death (and after their crimes). They realize they've arrived too soon in Hitler's personal timeline, and find a bigger fish: The woman who killed the Doctor. Except that she hadn't done that yet, either.
- One episode of Hercules: The Legendary Journeys had Iolus given a chance to kill a man who had raped and killed a family. The catch was that Iolus had been transported in time before that man had committed any crimes. Meaning Iolus had killed an innocent.
- Seven Days occasionally had Frank preventing a crime as the episode's plot. Every episode, Frank is sent back in time seven days to prevent whatever disaster has happened. Sometimes he's able to do it by preventing the perpetrator from attempting the crime. Most episodes, however, this trope is subverted, and Frank has to stop the crime/disaster as it happens instead of preventing it from being attempted.
- During episode "Obsession" of Sliders, the main characters travel to a world where ten percent of the population have Psychic Powers. Amoung the various powers, is precognition.
- A bit of research into the history of this world reveals that psychics became popular when one warned Abraham Lincoln about his impending assassination, allowing Booth to be captured before the attempt.
- The Police Oracle identifies Arturo and Rembrandt as people who will kill Wade Wells, so the police make a Preventative Arrest. A Bewildering Punishment to all four at first. Basically, they're taken to the station, booked, and then released. If someone were to actually commit the crime, the police would have to chase them down, but otherwise the two are free to do whatever they want. This is all a Batman Gambit by the old Prime Oracle to make sure his successor is a compassionate man in addition to already being a powerful one.
- Star Trek: Voyager had an episode named "Relativity", where the 29th century timeship Relativity is attempting to stop a time-paradox sabotage attempt on the 24th century spaceship Voyager. After the culprit responsible for the mess is found, two earlier versions of the culprit are arrested. The Captain assures Captain Janeway that the three would be "integrated" into one person before his trial.
- Futurama parodied Minority Report in an episode where Fry joined the police's Future Crimes division.
- In a The Simpsons Treehouse of Horror segment, Milhouse goes on a Roaring Rampage of Revenge against students who wronged him in the past. When he's about to humiliate a kid, who says today is their first day at the school, Milhouse says the kid will do something bad to him in the future, so he's still going to need revenge. ("It's called pre-venge!")
