From my perspective, that's a feature not a problem. It's obvious what you're doing, and of you try to photograph something really inappropriate, I can always slap the phone out of your hand. With snapchat (or google glass) style specs, I essentially need to attack your face to stop you filming, a far more aggressive action. I'd love to be able to bank on people knowing when not to film, but theres always one shitbag at every emergancy callout trying to get a really gnarly shot of someone elses broken arm so they can get dank internet points from their friends.
