>> To take a photo of someone, you usually need their permission. Still ambiguous. What level of permission do you need? Verbal permission? "Verba volant", they might change their mind and claim later that they didn't agree to the photo? Signed permission? "Hey, mister, could you please sign this document that states you agree with me taking a picture of you?". That's a private contract, only slightly more useful than a verbal agreement because it can be contested in court. Formal contract signed by both parties and ratified by a public notary? That's the strongest form of agreement but how practical is it for taking a picture on a bus? Seems to me that like many laws, this one too is more for intimidation than practicality. I forgot how these are called (if they even have a name), these ambiguous laws that specify something fuzzy without a clear way of enforcing it and vague penalties. Reminds me of the (Hacker News?) story of the guy in Japan who refused to pay the TV tax (can't find it of course, or I'd have posted it here) and was threatened by "penalty", only problem is it says nowhere what the penalty is and who collects it.
