Do you believe that there is any danger in a government deciding to target criminals who they think might likely commit a crime in the future (but haven't yet)?

Yes because there are so many factors that can change before that time comes. plus every person by law is innocent until proven guilty in a court of law. And for that to happen they would need hard evidence to prove or convict that they were going to do it.

explanation:

well stockyards mean a large yard containing pens and sheds, typically adjacent to a slaughterhouse, in which livestock is kept and sorted. and i'm assuming that by party you   mean a large group of people which does make sense because chicago is a very crowded place much like new york. stockyards tend to take up a lot of room due to needing the area for pens to keep animals in and the fact that stockyards are usually right by slaughterhouse where they process and distribute the product. so its much like a zoo but with some dead animal products close by.
