There are different technologies. The "old" new screening technology which produces the "naked" image, and the "new" new screening technology which reveals the internal details. The "new" new is what they're discussing to counteract the internal hidden explosive device. You won't have been through one of these. The "old" new is what you would have gone through at CLE.
