Ask HN: carry a gun, wear Google Glass?

Looking at the Zimmerman case, I think that if I were living in a country that permitted armed self defense[1], I'd be trying my damndest to get my hands on Google Glass.

Assuming for a minute that events in the Martin shooting transpired the way Zimmerman said they did, it would have been to his definite advantage to have been wearing Glass and have recorded events as they transpired.

So, for those HN folks who go armed - with firearms or otherwise - would you consider using Glass in this fashion?

[1] I live in Australia, where self defense of any sort is frowned upon, and armed self defense will land you in a world of legal hurt. Decent folk who go armed here tend to fly under the radar: umbrellas, canes, torches, that sort of thing.
