Speaking of which: how have things gone with the UK's experiment?
Maybe I'm not plugged into the right channels, but I haven't heard any news about "London falsely jails thousands of people due to false-positives on the camera surveillance network" or "the Crown finds and jails protesters by the thousands."
Last I heard, it got mired in legal issues, and was recently tossed out by the courts [0]. (Something that's not quite as likely in the US due to the EU being more privacy-conscious, and would require mass outrage and an act of congress to deflect)
