New York Post
reports of this incident at LaGuardia on 3/22/11. The passenger, who is identified as Nancy Campbell, a 33 year old urban planner from Brooklyn, was apparently travelling alone when, having already cleared security, she was attacked by a TSA agent:
... approaching the gate when the young agent stopped her, told her to drop her stuff and demanded she stand spread-eagled.
As passers-by gawked, the TSA agent patted Campbell down, touching her breasts, inner thighs and crotch, the freaked-out flier told The Post.
When she protested, the agent said, "You can either continue on flailing about, or you can let me do my job. If you don't, you can't fly.
Please note: I use the words "assaults" and "attack" in this post deliberately and not ironically, and with full knowledge and consideration of what those words mean.
