This is a special scanner where the airline passenger steps into the device by himself or herself, a device with especially solid, opaque sides and doors. The doors close and there is complete privacy during the scan. No one ever looks at the x-rays. If, during the scan, the device detects a bomb on the subject, the device causes the bomb to explode.
The device requires only one TSA-like person. He stands outside the device, of course. This person is equipped with a dust pan and broom, in case the bomb goes off and the inside of the device needs to be swept out in order to prepare it for the next passenger.
