Majority Report

There's a poll running on CNN.com right now related to the recent shenanigans occuring on the Korean peninsula: "Is a preemptive strike to destroy a nation's nuclear weapons capability ever justified?" (can't link because it's a javascript poll.) As of 2:45 PT on October 9 2006, 58% (40161 votes) say "yes."

There are a lot of reasons why I would say "no," but instead I offer the Minority Report question: Is arresting a person for a crime they have not yet committed ever justified?
