I keep reading about people being upset that somebody is wearing Google Glasses and recording them.  
I don't understand.  
In most stores and on many streets there are cameras recording you and me.  In a recent accident the security camera showed I was in the right.  But, more importantly it means I was being recorded.
When you're out and about how many people talking (supposedly) on their cell phones are actually recording you?
What is the fear of being recorded in public?  If you were in your back yard or in your home I would understand.  But what is the harm of being recorded by ONE MORE device in PUBLIC?  What are these people doing in public that they are so upset about being recorded?
Or maybe, who are they?  Are they criminals that fear being found?
