Drugs have been largely a tool by the government to justify aggressive searches of poor people. I don't think the justice system we have can work only with only the search justifications of terrorism, child pornography, and intellectual property theft. Maybe I'll be surprised, though.

Maybe hate speech/bullying will be the new frontier. We have to know what everybody is reading and writing to make sure they aren't hating: "my dog alerted to the smell of a flash drive."
