Many experts and critics suspect that the full-body “naked scanners” recently deployed at U.S. airports do little to make us more secure, and a lot to make us angry, embarrassed and late. For instance, the scanners can’t see through skin, and so weapons or explosives can be hidden safely in body cavities.
But this is government we’re talking about. A program or product doesn’t need to be effective, it only needs to have a good lobby. And the naked-scanner lobby is small but well-connected.
