TransWorldOne....take a deep breath and think this through. Here you have a 71 year old lady who suddenly remembers she has forgotten an article of clothing and turns around to retrieve it. She probably doesn't travel often and isn't totally aware of recent airport security changes.
She wanders a few yards into the secure area, never out of sight of TSA....and their reaction is to call in bomb sniffing dogs, close the terminal and haul her to the police station??
What dastardly criminal act did she commit that leads you to believe she should hang her head in shame??
