USA Naked scanners and lobbyists

There is an interesting article that a friend directed me to on naked body scanners in the Washington Examiner. It's about how boby scanners do little to improve security (items can still be hidden in body cavities) and the strong lobby in the states that has ensured it's rollout accross US airports.

A point that the above article does not touch on is how safe are these boby scanners. They use a short but very high dose of exposure to X-ray's. See AFP's 'Naked' scanners at US airports may be dangerous: scientists. I do hope the rush to get these machine in use at airports has not exposed people to a high dose of x-rays as well as exposing their civil liberties.
