Once again I think that the engineering community have accomplished a great feat in isolation. This will not be universally accepted since there are many cultures that even object to the physical pat down search method. As a pilot I very much want to do whatever is necessary to ensure the safety of flight but we need to make sure we find a solution that fits everyone so that we have people in the seats to pay our salaries. I find that moving down pathways like this distract our engineering community and slow down the process. If we are truely interested in finding the right solution lets not stop halfway.
