don't be a glasshole

Bring a camera into a dive bar and refuse to stop filming, you should expect trouble. I'm surprised the Google Glasses weren't destroyed.
Google glass records audio and video, so they should be illegal to use on private property, especially without notice, just like any other audio recorder.

You may not raise your hands to a person just cause they're being annoying. It's called battery. If you own a business you can ban these things or kick the people out who use them. You may not beat the shit outa them and introduce the random chance that you might kill a mother fucker just cause they annoy you.

I fully agree, the reaction was unreasonable and illegal. I understand I may have sounded like I was excusing the attack, I did not mean to.
My point was you should not assume people will act reasonably, respectfully, or even legally when they are 1.drunk and 2. you are continuing to antagonize them (illegally?) by recording their drunkenness after being asked to stop. They had no right to assault or rob her, but it was easily foreseeable that something like that would happen. The same would probably happen if she were 'demonstrating' a full size video camera in the bar, but the glasses make it too easy to forget that's what they are.
The bartender should have foreseen the escalation, taken control right away and made her put them away or leave, then there would be no problems. The bar may be in trouble for not doing that in the end.
The fact that google had to put a public warning up about this shows me it's a big issue they need to address and not leave it solely up to their users to act properly...I'm not sure how they might do that...red record light maybe, so you can show you aren't recording?
Perhaps I'm wrong, but as I understand it you are still not allowed to record audio of others without consent on private property (or many public properties), and these people obviously didn't consent.

Moving this video to shagen454's personal queue. It failed to receive enough votes to get sifted up to the front page within 2 days.

Simple bad-call call not exercising decorum with a view to self-preservation in one's choice of environs. My first guess as to who would wander into a jungle without gear or guide?? Clueless white people most likely.
