Is there any reason to frisk children at airport security checkpoints?

On April 12, a video surfaced on YouTube of a 6-year-old girl getting a security pat-down by a Transportation Security Administration officer at New Orleans’ Louis Armstrong International Airport.
A week earlier, an 8-year-old boy was given a full pat-down at a security checkpoint at Portland International Airport.
After a public outcry questioning their actions, TSA officials have said that in both incidents, the officers were following proper protocol.
In response to the New Orleans incident, Rep. Jason Chaffetz (R-UT) wrote a letter to TSA Administrator John S. Pistole, claiming the agency violated its policy that prohibits pat-downs being conducted on children under the age of 13.  However, TSA spokesman, Nick Kimball, said there is no such policy.
While some view the pat-downs as unnecessary, others think an exception might create a security loophole that terrorists can exploit.
Do you think small children should be exempt from TSA pat-downs?
