>>3593355Doesn't matter. You're given no expectation of privacy when in public and expecting it is absurd. Unless you live somewhere like Germany you don't need permission to photograph other people.
I've been harrassed a couple of times because people thought I was photographing them when I wasn't. It's always ugly, fat, disgusting old people who get bent out of shape over it. Nobody wants your picture at all fucker, so stop worrying about it.
