"The Chicago Police Department is mis-applying epidemiological science (the study of entire populations) to target individuals in a real-life version of Minority Report. They have decided that it is a good idea to put people on a secret list based on a Big Data analysis of their social networks. But don't worry, it isn't racist or abusive because, Science!"
If the data is there, and the technology to analyze it is there, isn't it foolishness to think that it won't be used?
That is the perfect justification for authoritarianism. There are all kinds of things that we as a society choose to prevent our government from doing because they are not compatible with a free society. A democratic government is not some indepdent creature, it exists solely at the whim of the citizenry.
