I have changed my mind on this topic recently. I believe that when you video in public everyone that gets videoed should require explicit permission or their face and voices should be removed. The only exceptions would be videoing public servants and if a crime is being committed. Videoing for private consumption would also be allowed in my opinion but not if it's posted in a way that more than a handful of people could see or if its uploaded to a site.

With AI this is entirely possible and if you are going to post videos on youtube or anything, you should be able to afford the removal of non-verified participants.
