The same applies to facial recognition. The technology will improve and it behooves us to be making sure that when it does end up in daily life we made sure it does behave in the best interest of all. This means making sure mismatch issues don't get brushed aside or hidden and its all out in the open to see how it works.

Don't fool yourself into believing a few cities and even states declaring that it is not allowed, that has never stopped the intelligence community before and certainly won't going forward. Too many will buy into the idea that even a law at Congressional level will do anything but so many exclusions exist and so much is permitted under completely innocent sounding legislation you can never be sure.
