A Pre-crime system would benefit society

The explanation for the pre-cogs is flawed. You have used the example of a man killing his wife for cheating on her. He intends to kill her, but his movements are predicted and he is arrested. he did not kill her. Going back to the moment, he wasn't going to kill her because he was going to be stopped. This flaw means that the pre cogs must predict all possible futures and find the most likely and relevant, then remove the ones where the person is arrested and display it. Since there is an infinite number of universes with infinite versions of the event, this feat is impossible. Now, the biggest problem with the pre crime system, I will call the Slave to Fate argument. So lets say your "Oracle", sounds better than Pre-Cog anyway, is in fact a machine that does predict the optimum future and does in fact predict the police arresting the person. This machine has one flaw already; Since it detects crimes, it must already follow a system of law. An easy task if the world is under one flag as in Minority Report, but laws are different in every society. Would the oracle predict homosexuals in Iraq? Which country would own the Oracle, or would each have one? These are open ended questions I know, but they are flaws in the system nevertheless. The only solution to the laws problem is that the Oracle predicts all events, and a filter of specific laws is then applied. This opens a door to a whole new set of problems that come with future predictions. If the predictions that happen are countered, the Oracle will simply predict the counter happening. This means that Fate will become an established thing that cannot be fully altered. Supposing that a politician wishes to use it to his advantage? He would be arrested yes, but what if the Oracle predicted the scientist working the Oracle accepted a bribe? Would he report that? And you've said that the Army is notified too. I feel safer already. No one is more trustworthy with time altering powers than the US military. Snowden releasing their surveillance was a crime. Their spying was not. Do you now see how this prediction could be used by authorities such as the military and politicians to control opposition? There must be someone of absolute standards who controls the Oracle alone. Someone of absolute morals. A slave to fate, so to speak. The ultimate problem surfaces when the military commits a war crime, the Oracle predicts it, but the military is notified too. They make a move against the Oracle, which the Oracle predicts, all the while the police are powerless since they can't stop an army. The Oracle predicts that alerting the police would be a crime since revealing military secrets is illegal. The Oracle then predicts the military taking over the Oracle, something no one can stop. The military can now establish total domination over all the US's enemies and predict their actions, essentially ruling the world. The world now under one flag, the Oracle can finally predict for the whole world, but under the new filter of the US military. The masters of time destroy their enemies while their enemies cannot raise a finger without the Oracle knowing. Your pre crime system will inevitably lead to military dictatorship. So stick that in your minority report and write it.
