Chicago starts warning citizens about crimes they might commit.
techdirt.comWhen I watched "Minority Report", I enjoyed it but said, "There's no way sane people will allow this." I'm wrong again.
I think it's a bit different when they're using it to discourage, rather than for enforcement.
As a side note, Minority Report film was changed in some... interesting ways from the short story. Like, most ways. I recommend reading it. Not that either should serve any sort of evidential purpose...
