I am looking forward to a wider release of google glass for reasons like this. I can't easily jump into my pocket and pull out my phone to film a cop without, probably, getting shot but to be able to have it ready to go with some sort of motion/voice activation... will be so great.
I understand where you are coming from but if I was at a bar and someone was wearing a Google glass I'd be pissed too. There are just some activities you would like to enjoy without feeling like there are eyes on you (yes there are security cameras in the bars). Hopefully the real dive bars won't see a glass patron for another year or so.
