the quandaries posed by the question of why not restrain an individual who might commit a crime in the future if we think it can be predicted illustrates the premise of the movie minority report:

(which, by the way, was intended to be science fiction).
I’m guessing you never read the short story. In it, Anderton has read the three reports.. The initial report of the murder of Kaplan, the second report where he runs and Kaplan uses the false prediction to overthrow the government and institute martial law, and the third where he kills Kaplan to prevent that from happening.
The story was much less a warning and more about choosing the lesser of two evils. Anderton decided that killing a man and himself and his family being exiled off planet was better than Kaplan’s authoritarian future.
The better connection is the secret enemies lists of Hoover. This is just a new variation on a very old system, and one I’m sure the Dixie Mafia will judiciously use should Bill Clinton get a third term as president.
