law enforcement officers.....demonstrate an actual and continuing threat to their safety posed by an arrestee, or a need to preserve evidence related to the crime of arrest from tampering by the arrestee, in order to justify a warrantless vehicular search incident to arrest conducted after the vehicle's recent occupants have been arrested and secured.

So are people who travel a lot going to be subjected to dangerous levels of radiation if they get backscattered too often?

Most experts say no. According to the Health Physics Society (HPS), a person undergoing a backscatter scan receives approximately 0.005 millirems (mrem, a unit of absorbed radiation).

American Science and Engineering, Inc., actually puts that number slightly higher, in the area of .009 mrem.

According to U.S. regulatory agencies, 1 mrem per year is a negligible dose of radiation, and 25 mrem per year from a single source is the upper limit of safe radiation exposure.

Using the HPS numbers, it would take 200 backscatter scans in a year to reach a negligible dose -- 1 mrem -- of radiation.

You receive 1 mrem from three hours on an airplane, from two days in Denver or from three days in Atlanta. And it would take 5,000 scans in a year to reach the upper limit of safety.

A traveler would have to get 100 backscatter scans per week, every week, for a year, in order to be in real danger from the radiation.

Few frequent flyers fly that frequently.

Someone was complaining about "the Left's" problems with the militarization of our so-called foreign policy? These kinds of things make it increasing clear - if it wasn't before - that we don't need the Weathermen to "bring the war back home" anymore; we as nation have opted for bringing the war back home. And as the technology of destruction advances and the enemies increase, the more the security state will move in the direction of perpetual high alert.
