I don't disagree that it's potentially a problem, I'm just saying that as someone recording in a public place you're unlikely to be running afoul of wiretap laws. We should be far less concerned about personal cameras (wearable and/or phones) than fixed security cameras, anyway. We're probably on a fixed CCTV 100X as often as we're being recorded by personally-carried cameras. Worry about Glass and other such devices is just a red herring.
