I think you're missing the point. Technology is going to continue to improve, components will continue to shrink, and cameras will become ever-more portable and concealable. These are trends that cannot be stopped. Google Glass is only one point along a continuum, and slapping a red LED on it solves nothing. It's already the case that you are recorded without your knowledge or consent on a regular basis. Whether you're browsing a department store or planting a bomb at a marathon, there's a chance you'll be caught on tape. Who knows what the world will be like in 10, 25, 50 years from now? We may be able to download a digital copy of memories from the brain, in which case every pair of eyes will be a video camera. An extreme example, I know, but the point is simple. We can waste time and money fighting against the inevitable, or we can accept the changes in our world and learn to live with them.
