@Sunshine31 - This is really a difficult situation that many of these TSA agents are in because they were told to do their job and are just following those orders.
They did not create the regulations. I know that the pat down procedure now excludes children, so at least they will not be subjected to it. From their point of view it would be easier for people to walk through the scanner, but many people do not want to be subjected to that radiation.
I really don’t have a problem with them checking adults, but I do think that it was a bit much when they checked children.
