You can absolutely still opt out of body scans. Talk about being unhelpful.
and sorry if you cannot understand why countering reports of the exception with the rule is not helpful. thats how you get things like whitelivesmatter.
If you can cite some evidence that your impression is the rule, that might be helpful. My own experience, having opted out and gotten the pat-down every time I've flown since the new scanners were introduced, is that the process has not really changed at all over the years, and opting out has never come close to causing a missed flight.
The TSA is as effective at keeping weapons out of secure airport areas as the tech industry is effective at keeping the CEO from clicking a phishing link.
