The real reason however is the 2nd part of IndyKid's statement above.
It is indoctrination for the masses. The are already accustom to the fact that at airports they will be blasted with x-rays, body searches, take off their shoes, can not carry xyz items, etc... It is a "common" thing for them and something that must be done WITHOUT QUESTION when at the airport.
The next step in the process is getting the masses use to the fact that TSA will now check their buses. A little while later it will be the trains and on and on.
Before you know it will be
just following orders as that mom and kid were domestic terrorist and did not want to pass a security checkpoint at the mall. I mean come on everyone passes thru the checkpoint.
Hitler & Muslim could never have dreamed this in their wildest dreams.
I wonder if those who served in WWII ever though it would come like this.
