&gt; If someone doesn&#x27;t want to be captured, too bad, they shouldn&#x27;t be throwing photons at you (read: if they want privacy, they shouldn&#x27;t be in a public location).<p>That is true when it comes to merely being seen, but not being recorded.  Being in a public location naturally implies consent to be <i>seen</i>, but it does not imply consent to be <i>recorded</i> artificially.  (This includes any augmentations to human abilities from future technology, as someone mentioned this in a later comment)
