Anyone else concerned with the amount of ignorance being spewed when it comes to Google Glasses?

I'm constantly seeing people talking about it being banned because it can 'secretly' take photos or videos Lots of comments of you are not allowed to take my pictures out in public, etc, etc.

I'm not sure what the laws are in other countries but in the States photographers have rights.

I even carry one of these with me in case i get hassled by someone or the cops.

I'm just disheartened by the ignorance and fear. We are talking about people walking around out in public. Out in PUBLIC. And they somehow think magically they still have the same rights to privacy as they do in their bedroom.
