Here's a video of a Chicago TSA operative searching a three year old boy who is in a wheelchair, wearing a body-cast, on the way to his family trip to Disney World. The boy's parents were not allowed to hold him or touch him to comfort him during the procedure.
A toddler in a wheelchair is stopped by the TSA at ORD (O'Hare Airport in Chicago) and forced to into a sequestered area. On his way to a family vacation in Disney, this 3 year old boy is in a body cast for a broken leg. Despite assurances from his father that "everything is ok", he is physically trembling with fear while he watches his two siblings, mother, father, grandfather and grandmother pass through along with everyone else...only to be singled out.
I write books. My latest is a YA science fiction novel called Homeland (it's the sequel to Little Brother). More books: Rapture of the Nerds (a novel, with Charlie Stross); With a Little Help (short stories); and The Great Big Beautiful Tomorrow (novella and nonfic). I speak all over the place and I tweet and tumble, too.
