Why You Can (And Should) Opt Out Of TSA Facial Recognition Right Now

We were told it was not optional coming home from an international flight last month. However, our toddler was with us and nervous and they said we could opt out for him. I said great, thanks. Picked him up while we were talking and I wasn't really thinking about where I was holding him. The agent looked over, smiled and said hi to get their attention, and I saw him take the image, seconds after we verbally opted out. Sigh.
