As more of the Rohde and Schwarz devices appear, it will require more opting out.
I have difficulty raising one arm but in principle don't object to MMW scanners. It's not the same as the older Strip Search Machines that delivered ionizing radiation with images so graphic a person had to be hidden away in a closed room to view them. Pre Check should help avoid these newer machines most days but I'm betting that TSA will phase out the WTMD in due time.
