I could see them still shutting down the airport because, after all, she was in the secure area with weapons, so maybe there are others there still, and you'd still risk a bureaucrat imposing his agency's version of "zero tolerance" and making an example of you. Also, I'm convinced that this woman's name is going into a database somewhere and she's going to have a very difficult time boarding a plane in the future. I'd rather stash the stuff in the trash. The airport shutdown could be avoided by stashing it in a trash can outside the secure zone. I bet they find stuff in those cans all the time as people realize they came to the airport with them by accident and toss them before they get to security.
And your point is?
If the fools choose to shut down the airport, that isn't *my* fault, and I shouldn't feel guilty for it.
I'd rather wait until I got off the plane, walked to "security," asked to speak with a supervisor about a sensitive subject, in private, and then tell them. This way you don't embarass TSA publically and provoke them into doing something to save face, you don't risk closing an airport, you don't risk setting off a flighty stewardess and you don't interrupt the rest of the world because the TSA are inept.
No.. All you risk is a felony arrest and having your life ruined.
If the Stasi operative is having a bad day, you might get charged.
If they don't like the way you look, you might get charged.
If they are getting pressure from Bush/Ashcroft/Mineta to improve their "stats" (as this administration loves to do), you might get charged.
But it's your life and you're welcome to do as you please.
As for me, the most important thing is that *I* make it home safely at night. I heard that from a police officer once, and it sounds like good advice.
