Forgive me if I'm wrong, but I believe the machines do take nude pictures but only show the analyzed image to the operator. Additionally, it's a question whether the machines make sense in regards to a cost-benefit analysis. Finally, privacy is still important and we shouldn't use tactics that are unnecessary. Funneling some percentage of users through the machines while allowing most to pass through metal detectors may be an effective strategy that doesn't involve analyzing nude photographs of every passenger.
