 Here's what they don't want you to know, okay, is that you don't really have to do this. You can opt out, okay? In case you're wondering, if you're a U.S. citizen, your photo is kept up to 12 hours after this verification. Now, if you're not a citizen, too bad for you. It's kept in the database. But as I mentioned, signs are supposed to be up that you can opt out. But I tell you, I went through TSA a couple weeks ago.
