I find it interesting that the backlash against public video is against Google Glass. We have no privacy in public. The Constitution guarantees us no privacy in public. We don't seem to care that people video us all the time in public with their cell phones. Have never heard a story where someone walks up to someone using their cell phone as a video camera and smashes it (several of those stories out about Google Glass). Cities have cameras everywhere. Many intersection have cameras. Most large city public spaces have cameras. Every public business, such as Walmart, Target, JC Pennys, the local Quickee Mart, the gun store, the bank, the mall, the drug store, Home Depot, McDonalds, you name it: it has video recording. We don't even think about that, even justify it in some cases for safety.
You do understand that the guy at Starbucks, using his laptop or appearing to tap out a text on his iPhone, or the gal using her tablet, could be recording, right along with the camera Starbucks is using!
Why is Google Glass any different than cell phone video and public video? I just don't understand.
