My uncle once had a sit-down with me that included his "eyes only policy": Looking is fine. Obviously gawking is rude. Any recording is at your own risk, to be shared with/bragged about with ABSOLUTELY NOBODY. And unless she's injured, don't you so much as put one finger on her without explicit permission. I followed the last one so strictly that it was months after me and my GF got serious before I stopped asking if I could hold her hand.
More people than you'd think have a stash of some kind...but you'll never know, because they're not idiots. The idiots are the ones who end up in the evening news, or wake up in the ER.
