Agreed. I vote to keep the groping done in public. That way, at a minimum, when the TSA goon grabs a private part, as he/she will certainly do, you can scream about it then, in public. To have that done in private it becomes your word against their word, with no witnesses and you likely being hauled off to some private room for additional screening (groping) and labeled a security risk.

The entire process sickens me. The idea that tens of millions of passengers will be subjected to such radiation every year, for no proven benefit is astonishing. And, to think that these machines will be calibrated correctly (when hospitals have huge problems calibrating their X ray equipment) is not realistic. They are taking poorly trained and poorly paid workers, providing them with sophisticated X ray equipment, and then letting them loose on the public with no real check. What are the long term exposure consequences? Where is the testing data? How reliable is that data? Who reviewed it?

Opt out? You then get open handed searches in various body cavities. Question the entire process and you are soft on terror.
