For those of you who travel in the united states, you’ll know they now have facial recognition scans when checking your id. You can opt out by telling them you don’t want to take the picture. I do every time, but I wonder what the point of the scan is if you can just opt out. That given, why do you think they do it? What prevents them from forcing you to do it?

To those of you who live outside of the united states, have you seen a similar increase in security at your airports?
