The more you let a government stick high resolution 3d cameras in your face and shrug it off because you’ve already lost privacy the stronger their database becomes, the more complacent you become, the more willing you become to let them do it at the train station, the post office, the crosswalk, etc. The more willing you become to put your palm on their palm reader and retina in their retina scanner when they deploy that technology. I’m not dismissing better avenues to focus efforts, I’m acknowledging the increase in surveillance and potential for abuse in the absence of any proven benefit to the people that are allegedly protected by these changes.
