"Stepping out the door means that we're on camera and we must perform correctly." well... wait a minute, why would you "perform" to begin with? Is this your MO to "perform" incorrectly? What are you getting at? Why create some artificial performance anxiety on a mere possibility that you might get judged? Or is it just a superimposition of your own habit onto potential onlooker that makes you pucker up and steals your comfort away?
"If you happen to see something you shouldn't while wearing Glass, a record of your sight will be available to the state to build a case against you." Um... that's crap, Sir! Unwarranted surveillance is inadmissible as court evidence. And there is this important difference between Sensing and Perceiving. You may Sense everything, but it doesn't mean that you have Perceived everything. And forcing anyone to admit that they have Perceived an event, and item, a person, or lack thereof, would be forcing them to incriminate self with perjury. Perception varies greatly depending on the state of mind and external factors, neither of which are relayed by a recording device. Ask any attorney.
And lastly, if you are so ferklempt by "someone is watching" possibility, consider this - anything with three letters for a name was given a legal permission to make recording of the color of shitstain in your bunched up knickers when "we the people" let Patriot Act take place. So why worry about Google, when you have everyone else counting hair follicles on your receding hairline through a slightly larger version of Glass mounted on a drone 30,000ft above you?
