Is it true now that police use facial recognition at protests? The answer to that is of course they can use facial recognition software and they do use facial recognition software very frequently in crowded areas. And what are they looking for? Well, they have databases now that can tell them whether or not you've got a warrant against you or whether or not you've got a criminal history of some sort. So you say, "Well, Dr. Judge, should I wear a mask?" No. Just know that it's out there and just realize that AI is changing everything.
