To me, widespread facial recognition isn't that different from an ID... except you're always obligated to walk with your ID taped to your forehead. Once the system is in place, expanding it to other locations could be a trivial task. Hypothetically, this leads to a situation where you can discretely "card" anybody by just recording them, with no need to ask for an ID or even let the person know that they're being checked. And if that's in place, then, given enough cameras, tracking every person's location is also simplified. So, I guess my opposition here isn't directed at specifically TSA, but rather creating a centralized facial recognition database in general.
