T. O. T. C.!
"Screeners "meet so many children every day, they may actually notice something that's out of character with a child."
Like a kid who is nervous because it is their first flight and they saw the flames from a plane crash last week on TV? I forgot, all screeners have a PhD in Child Psychology, too, in addition to the long list of other job skills.
How many planes have been hijacked by non custodial kids? Just wondering.
