A Pre-crime system would benefit society

Your arguments are, in themselves, contradictory. You argue that, due to each countries laws being different you would have to apply filters to the 'Oracles' for it to be able to detect the respect acts of crime, using the case of a widespread system to your advantage. Then you focus on the idea that, if the 'Oracles' utilised by the US government, they would be able to use it's predicting powers to essentially take over the world. You can't have your cake and eat it too. Either the system is widespread and multiple nations have adopted it and the idea of a Precrime system, as per your first argument, OR the system is not widespread and as such a military power (not necessarily the US, why does it always have to be the US?) who has access to it is able to use it to take over the world. If the system were present in other regions with differing laws then they too would have access to this information and it would effectively cancel each other out. Furthermore, I did not explicitly say that the military would have to be the back up system. As this idea comes from Minority Report I merely included from the example used in the text. Notably, in the story, the military does try to seize power from the police through the use of the Precrime system, however John Anderton is able to prevent this thanks to the premonitions of the Precogs. My point was that putting in place measures to prevent corruption (or at the very least minimise) corruption, would not be overly difficult. You are also still stuck in the paradigm where a person who has not committed a crime can not be arrested. The idea of the Precrime system is that they can be! In your argument you say "He intends to kill her, but his movements are predicted and he is arrested. he did not kill her." This is the exact reason why the Precrime system is beneficial. As I previously outline, it replaces the need for a long, arduous, post-crime detective case and trial, as well as saving the life of the victim. Your paradox about what the Precogs see is also easily resolved. You must consider the future as changeable, not set in stone, which is heavily discussed in Dick's story.Say you are at time A, in the present, and at this point the precogs predict an event, lets say a murder, at time B, somewhere in the future. At the time when the precogs predicted it, that event was still going to take place. However at time C, let's say 10 minutes after A when the prediction has been analysed, the fact that knowledge of the murder at time B is now available, and used to prevent means that an alternate time path is created, one that is indeed different to that predicted by the precogs, but only came about because of this prediction. Had it not occurred then everything would have happened as per normal and a tragic murder would have been committed. Furthermore, your assertion that there are infinite universes is based on scientific theory and although many scientists believe this theory to be true, it is still a long way from being fact. Finally, I would like to reassert the resolution as it stood when my opponent accepted at the start of the debate: A Pre-crime punishment system, such as that portrayed in Philip K. Dick's Minority Report, would be, overall, beneficial to society.This system is merely used to detect acts of crime (actually in Minority report it was just murder, but I'm not bothered by the idea of expansion). It is not used for politicians to get a leg up on their competition, and given the proper programming it never would be. As this is my last post I would like to thank Duncan for the debate, he has certainly provided thought provoking and challenging arguments and I wish him luck for the final round. I now leave the debate in his capable hands, and soon after the hands of the voters.
