Under 18s need no ID, and for six days now we have been told that "All Those With No ID" are the worst of the worst by the Toddler Scaring Agency blog squad. By definition now, the IDless are all criminals until proven otherwise. So all under 18's will be SSSS.
OTOH, the TSA must have hired some consultants in Classical Conditioning to advise how to raise the next generation as sheeple. Easy, "scare em often and start em young" to Respect/Fear everyone with a Badge and submit to the Au-tho-rah-tay of Badge Wearers who say "Papers Please and spread em". By the time this girl is 30, she will no longer cry or object, just meekly SUBMIT to the Homeland Security Badges whenever and whereever she encounters them.
