Sounds like a move in the right direction.

I agree with the concept of RBS, but my concern is implementation on the scale required by TSA.

As to the confusion on shoes on/off there is a simple solution, maybe our resident TSA folks can agree and pass it on. The TDC, already making the 18 or older call, could simply tell parents at the podium the children that are exempt from shoe removal. This would be long before they would even have to think about getting them off.
